2015-07-30MLK-10828 thermal: imx: update the temperature calibration data for i.mx6Bai Ping
According to the design team: After a thorough accuracy study of the Temp sense circuit,we found that with our current equation, an average part can read 7 degrees lower than a known forced temperature. We also found out that the standard variance was around 2C; which is the tightest distribution that we could create. We need to change the temp sense equation to center the average part around the target temperature. Old Equation: Temp = Troom,cal - slope*(Count measured - Count room fuse) Where Troom,cal = 25C and Slope = 0.4297157 - (0.0015974 * Count room fuse) New Equation: Temp = Troom,cal - slope*(Count measured - Count room fuse) +offset Where Troom,cal = 25C and Slope = 0.4148468 - (0.0015423 * Count room fuse) Offset = 3.580661 Signed-off-by: Bai Ping <b51503@freescale.com> (cherry picked from commit b3208903656816c0ec446318c96cd8d3a2314258)
2015-07-23MLK-11236 mtd: gpmi-nand: Fix nand runtime PM issueYe.Li
Because of the delay of auto suspend, the nand clocks are delayed to disable when calling the clk_set_rate. This causes the clk_set_rate failed on some platforms like 6q/6qp, and finally lead the NAND not working.

2015-07-23mmc: sdhci: fix low memory corruptionJiri Slaby
When dma mapping (dma_map_sg) fails in sdhci_pre_dma_transfer, -EINVAL is returned. There are 3 callers of sdhci_pre_dma_transfer: * sdhci_pre_req and sdhci_adma_table_pre: handle negative return * sdhci_prepare_data: handles 0 (error) and "else" (good) only sdhci_prepare_data is therefore broken. When it receives -EINVAL from sdhci_pre_dma_transfer, it assumes 1 sg mapping was mapped. Later, this non-existent mapping with address 0 is kmap'ped and written to: Corrupted low memory at ffff880000001000 (1000 phys) = 22b7d67df2f6d1cf Corrupted low memory at ffff880000001008 (1008 phys) = 63848a5216b7dd95 Corrupted low memory at ffff880000001010 (1010 phys) = 330eb7ddef39e427 Corrupted low memory at ffff880000001018 (1018 phys) = 8017ac7295039bda Corrupted low memory at ffff880000001020 (1020 phys) = 8ce039eac119074f ... So teach sdhci_prepare_data to understand negative return values from sdhci_pre_dma_transfer and disable DMA in that case, as well as for zero. It was introduced in 348487cb28e66b032bae1b38424d81bf5b444408 (mmc: sdhci: use pipeline mmc requests to improve performance). The commit seems to be suspicious also by assigning host->sg_count both in sdhci_pre_dma_transfer and sdhci_adma_table_pre.

2015-07-22MLK-11183 usb: chipidea: otg: complete state machine before cancel hrtimerLi Jun
When do usb driver module load and unload loop test for A-device, the hrtimer may be cancelled during otg state machine running, so after the hrtimer is cancelled, the otg state machine may start it again by adding a new timer, this will cause the hrtimer will be active after its function memory is freed by module unload. This patch is to fix it by trying to hold the fsm mutex lock before setting otg state to be undefined, then otg hrtimer will be cancelled after current otg fsm transition completes, and no new timer will be added.

2015-07-22MLK-11269-2 usb: chipidea: host: avoid check PORT_SUSPEND wronglyPeter Chen
At some situations, the ehci_bus_suspend may not set PORT_SUSPEND due to port is not enabled, so add flag ehci->bus_suspended to check if ehci_bus_suspend set PORT_SUSPEND or not. We see "ci_hdrc ci_hdrc.0: timeout waiting for SUSPEND" wrongly when plug in an unsupported usb device, in that case, the PORT_PE is cleared and bus_suspend is called.

load/unload module The interrupt may occur (due to remove process may block interrupt) after we remove hcd, in that case, we should not call hcd's interrupt handler, otherwise, below NULL pointer dereference will occur, the reason for this is we call free_irq later than hcd's. So after hcd has been removed, we should not call hcd interrupt handler. ci_hdrc ci_hdrc.0: remove, state 1 usb usb1: USB disconnect, device number 1 ci_hdrc ci_hdrc.0: USB bus 1 deregistered [<800691e8>] (handle_irq_event) from [<8006c02c>] (handle_fasteoi_irq+0x84/0x14c) [<8006c02c>] (handle_fasteoi_irq) from [<800687f4>] (generic_handle_irq+0x2c/0x3c) [<800687f4>] (generic_handle_irq) from [<8000ed4c>] (handle_IRQ+0x40/0x90) [<8000ed4c>] (handle_IRQ) from [<8000856c>] (gic_handle_irq+0x2c/0x5c) [<8000856c>] (gic_handle_irq) from [<80012240>] (__irq_svc+0x40/0x70) Exception stack(0x80db1f18 to 0x80db1f60) 1f00: 80db1f60 3b9aca00 1f20: 06f86934 0000000d 80dbe1c8 80dbe1c8 ee71e0d0 00000000 06f5bb01 0000000d 1f40: 80db0000 00000000 00000017 80db1f60 00000009 8049c19c 000d0013 ffffffff [<80012240>] (__irq_svc) from [<8049c19c>] (cpuidle_enter_state+0x54/0xe4) [<8049c19c>] (cpuidle_enter_state) from [<8049c2e0>] (cpuidle_idle_call+0xb4/0x14c) [<8049c2e0>] (cpuidle_idle_call) from [<8000f07c>] (arch_cpu_idle+0x8/0x44) [<8000f07c>] (arch_cpu_idle) from [<8006876c>] (cpu_startup_entry+0x100/0x14c) [<8006876c>] (cpu_startup_entry) from [<80d52b10>] (start_kernel+0x350/0x35c) --[ end trace 1160f590a7b228b3 ]-- Unable to handle kernel NULL pointer dereference at virtual address 000000b0 pgd = 80004000 [000000b0] *pgd=00000000 Internal error: Oops: 17 1 PREEMPT SMP ARM Modules linked in: ci_hdrc_imx usbmisc_imx ci_hdrc udc_core ehci_hcd phy_mxs_usb mxc_v4l2_capture ipu_bg_overlay_sdc ipu_still ipu_prp_enc adv7180_tvin ipu_csi_enc v4l2_int_device ipu_fg_overlay_sdc mxc_mlb mxc_dcic evbug [last unloaded: phy_mxs_usb] CPU: 0 PID: 0 Comm: swapper/0 Tainted: G W 3.14.38-usb-host-otg-02047-ga4dec77 #13 task: 80dbbae8 ti: 80db0000 task.ti: 80db0000 PC is at usb_hcd_irq+0x4/0x38 LR is at handle_irq_event_percpu+0x50/0x180 pc : [<8040eed8>] lr : [<8006907c>] psr: a00d0193 sp : 80db1e98 ip : fffffffa fp : 00000000 r10: 80e1f13f r9 : d8009900 r8 : 0000004b r7 : 00000000 r6 : 00000000 r5 : d800995c r4 : d8f2dec0 r3 : d2234010 r2 : d2234010 r1 : 00000000 r0 : 0000004b Flags: NzCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment kernel Control: 10c53c7d Table: 6920004a DAC: 00000015 Process swapper/0 (pid: 0, stack limit = 0x80db0238) Stack: (0x80db1e98 to 0x80db2000) 1e80: d2234010 8006907c 1ea0: 0000004b ee71da00 d8009900 d800995c d8f2dec0 f4a00100 06f5bb01 0000000d 1ec0: 80db0000 800691e8 d8009900 d800995c 00000000 8006c02c 8006bfa8 0000004b 1ee0: 0000004b 800687f4 80dace54 8000ed4c f4a0010c 80db8970 80db1f18 8000856c 1f00: 00000009 8049c19c 000d0013 ffffffff 80db1f4c 80012240 80db1f60 3b9aca00 1f20: 06f86934 0000000d 80dbe1c8 80dbe1c8 ee71e0d0 00000000 06f5bb01 0000000d 1f40: 80db0000 00000000 00000017 80db1f60 00000009 8049c19c 000d0013 ffffffff 1f60: 06f86934 0000000d 80dc4a54 ee71e0d0 80db8574 ee71e0d0 00000000 00000000 1f80: 00000000 80e797f8 80dbe1c8 8049c2e0 00000000 80db0000 80db8574 806fe48c 1fa0: 80db0038 80e1f13d 80e1f13d 8000f07c 00000000 8006876c ffffffff 80d52b10 1fc0: ffffffff ffffffff 80d5258c 00000000 00000000 80d9ef30 00000000 10c53c7d 1fe0: 80db84fc 80d9ef2c 80dbcb80 1000406a 412fc09a 10008074 00000000 00000000 [<8040eed8>] (usb_hcd_irq) from [<8006907c>] (handle_irq_event_percpu+0x50/0x180) [<8006907c>] (handle_irq_event_percpu) from [<800691e8>] (handle_irq_event+0x3c/0x5c) [<800691e8>] (handle_irq_event) from [<8006c02c>] (handle_fasteoi_irq+0x84/0x14c) [<8006c02c>] (handle_fasteoi_irq) from [<800687f4>] (generic_handle_irq+0x2c/0x3c) [<800687f4>] (generic_handle_irq) from [<8000ed4c>] (handle_IRQ+0x40/0x90) [<8000ed4c>] (handle_IRQ) from [<8000856c>] (gic_handle_irq+0x2c/0x5c) [<8000856c>] (gic_handle_irq) from [<80012240>] (__irq_svc+0x40/0x70) Exception stack(0x80db1f18 to 0x80db1f60) 1f00: 80db1f60 3b9aca00 1f20: 06f86934 0000000d 80dbe1c8 80dbe1c8 ee71e0d0 00000000 06f5bb01 0000000d 1f40: 80db0000 00000000 00000017 80db1f60 00000009 8049c19c 000d0013 ffffffff [<80012240>] (__irq_svc) from [<8049c19c>] (cpuidle_enter_state+0x54/0xe4) [<8049c19c>] (cpuidle_enter_state) from [<8049c2e0>] (cpuidle_idle_call+0xb4/0x14c) [<8049c2e0>] (cpuidle_idle_call) from [<8000f07c>] (arch_cpu_idle+0x8/0x44) [<8000f07c>] (arch_cpu_idle) from [<8006876c>] (cpu_startup_entry+0x100/0x14c) [<8006876c>] (cpu_startup_entry) from [<80d52b10>] (start_kernel+0x350/0x35c) Code: 11a002a0 03a00001 e12fff1e e92d4008 (e59130b0) --[ end trace 1160f590a7b228b4 ]-- Kernel panic -

2015-06-30MLK-11178-01 thermal: add a check to avoid orderly_poweroff twiceBai Ping
When temperature >= the 'critical_trip' temperature, the common framework code will call 'orderly_poweroff' function to power off the system. During the power off procedure the thermal framework will go on polling the temp, this will lead to recall the 'orderly_poweroff' again. In the first poweroff flow, some system resource has been freezed, then if the secondary 'orderly_poweroff' frees the resource again, it will lead to kernel dump.

2015-06-24MLK-11137 usb: chipidea: host: add own hc_driver for each hcdPeter Chen
There are several benefits for doing like this: - hc_driver can be customized for each hcd - Other hcd hc_driver's initialization will not affect current one. We run out NULL pointer dereference problem when one hcd is started by module_init, and the other is started by otg thread at SMP platform. The reason for this problem is ehci_init_driver will do memory copy for current uniform hc_driver, and this memory copy will do memset (as 0) first, so when the first hcd is running usb_add_hcd, and the second hcd may clear the uniform hc_driver's space (at ehci_init_driver), then the first hcd will meet NULL pointer at the same time.
