2017-08-14ARM: dts: dra7xx: Enable NAND dma prefetch by defaultFranklin S Cooper Jr
Currently the default method of prefetch polled shows the highest possible read and write speed when minimal non NAND background activity is being done. But it is also very CPU intensive to reach these high speeds (CPU load of 99% via mtd performance tests). While DMA prefetch only uses 50% of the CPU to achieve around 23% less in top read and write performance. However, as the non NAND CPU load increases the read and write performance takes a large hit when using polled prefetch. Therefore, prefetch dma mode ends up outperforming prefetch polled in general "system level" test. So switch to using dma prefetch by default since it is likely what most users would prefer.

2017-01-05ARM: dts: dra7-evm: Remove pinmux configurations for erratum i869Sekhar Nori
Pinmuxing for DRA7x/AM57x family of processors need to be done in IO isolation as part of initial bootloader executed from SRAM. This is done as part of iodelay configuration sequence and is required due to the limitations introduced by erratum ID: i869[1] (IO Glitches can occur when changing IO settings) and elaborated in the Technical Reference Manual[2] 18.4.6.1.7 Isolation Requirements. Only peripheral that is permitted for dynamic pin mux configuration is MMC and DCAN. MMC is permitted to change to accommodate the requirements for varied speeds (which require IO-delay support in kernel as well). DCAN is a result of i893[1] (DCAN initialization sequence). DCAN pinmux is retained in this patch. MMC pinmux is missing from the dra7-evm.dts file and the board is relying on configuration done by bootloader. A subsequent patch will add MMC pinmux configuration. A side-effect of this patch is that NAND support is removed. NAND pins clash with VOUT3 on DRA7-EVM. U-Boot selects VOUT3 over NAND as per TI EVM application needs.

2016-04-26ARM: dts: dra7x: Remove QSPI pinmuxVignesh R
DRA7 family of processors from Texas Instruments, have a hardware module called IODELAYCONFIG Module which is expected to be configured. This block allows very specific custom fine tuning for electrical characteristics of IO pins that are necessary for functionality and device lifetime requirements. IODelay module has it's own register space with registers to configure various pins. According to AM572x TRM SPRUHZ6E October 2014–Revised January 2016[1] section 18.4.6.1 Pad Configuration, in addition to pinmuxing(MUXMODE), when operating a pad in certain mode, Virtual/Manual IO Timing Mode must also be configured to ensure that IO timings are met (DELAYMODE and MODESELECT fields of pad's IODELAYCONFIG module register). According to section 18.4.6.1.7 Isolation Requirements of above TRM, when reprogramming MUXMODE, DELAYMODE, and MODESELECT fields, there is a potential for a significant glitch on the corresponding IO. It is hence recommended to do this with I/O isolation (which can only be done in initial stages of bootloader). QSPI is one such module that requires IODELAY configuration. So, this patch removes the pinmux for QSPI for DRA74/DRA72 EVM as it needs to be done in bootloader (U-Boot) and cannot be done in kernel. Users should migrate to U-Boot v2016.05-rc1 or higher.

2016-04-26ARM: dts: AM57xx/DRA7: Update SoC voltage rail limits to match data sheetNishanth Menon
As per the data sheet starting from SPRUHQ0H (Nov 2015 - Latest[1]), VDD_CORE can vary from 0.85v to 1.15v for AVS class0. VDD GPU/DSP et.al. can range from 0.85v to 1.25V with AVS class0 Since dynamic voltage scaling is disabled for DRA7/AM57xx SoCs for all SoC rails other than MPU, the bootloader is responsible for setting up the AVS class0 voltage, however, with wrong voltage machine constraints in dtb, regulator framework will lower the voltage below the required voltage levels for certain samples in production flow. This can cause catastrophic failures which can be pretty hard to identify. Update board files which don't match required specification.

The binding definition for the PCF857x GPIO expanders doesn't mention a "ti,pcf8575" compatible string. This is apparently because TI is only a second source - there is no functional difference between PCF8575 chips manufactured by TI and NXP, and the same board might be populated with either depending on availability. This is not a problem in practice because the I2C core uses of_modalias_node() before matching drivers and this strips the manufacturer name.
