git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/late
SoC glue layer changes for SGX on omap variants for v5.4
For a while we've had omap4 sgx glue layer defined in dts and probed
with ti-sysc driver. This allows idling the sgx module for PM, and
removes the need for custom platform glue layer code for any further
driver changes.
We first drop the unused legacy platform data for omap4 sgx. Then for
omap5, we need add the missing clkctrl clock data so we can configure
sgx. And we configure sgx for omap34xx, omap36xx and am3517.
For am335x, we still have a dependency for rstctrl reset driver changes,
so that will be added later on.
Note that this branch is based on earlier ti-sysc branch for omap36xx
glue layer quirk handling.

I've tested that the interconnect target module enables and idles
just fine when probed with ti-sysc with PM runtime control via sys:
# echo on > $(find /sys -name control | grep \/5601)
# rwmem 0x56000024
0x56000024 = 0x00010200 # SGX540 CORE_REVISION
# echo auto > $(find /sys -name control | grep \/5601)
# rwmem 0x56000024
And when idled, it will produce "Bus error" as expected.

We can now probe devices with ti-sysc interconnect driver and dts
data. Let's drop the related platform data and custom ti,hwmods
dts property.
As we're just dropping data, and the early platform data init
is based on the custom ti,hwmods property, we want to drop both
the platform data and ti,hwmods property in a single patch.

We currently don't know if a revision register exists or not. Zero is
often a valid offset for the revision register. As we are still checking
device tree data against platform data, we will get bogus warnings with
correct device tree data because of incomplete platform data.
Let's fix the issue by using signed offsets and tag the revision registers
that don't exist with -ENODEV, and init the missing ones with the correct
revision register offset.

We support decoding the bootloader values if DEBUG is defined.
But we also need to change the struct omap_hwmod flags to have
HWMOD_INIT_NO_RESET to avoid the GPMC being reset during the
boot. Otherwise just the default timings will be displayed
instead of the bootloader configured timings.
This also allows us to clean up the various GPMC related
hwmod flags. For debugging, we only need HWMOD_INIT_NO_RESET,
and HWMOD_INIT_NO_IDLE is not needed.

Commit 9a1091ef0017 ("irqchip: gic: Support hierarchy irq domain")
changed the GIC driver to use a non-legacy IRQ domain on DT
platforms. This patch assumes that DT-driven systems are getting
all of their interrupts from device tree.
Turns out that OMAP has quite a few hidden gems, and still uses
hardcoded interrupts despite having fairly complete DTs.
This patch attempts to work around these by offering a translation
method that can be called directly from the hwmod code, if present.
The same hack is sprinkled over PRCM and TWL.
It isn't pretty, but it seems to do the job without having to add
more hacks to the interrupt controller code.
Tested on OMAP4 (Panda-ES) and OMAP5 (UEVM5432).

- omap mmc driver supports multiplexing, omap_mmc_hs doesn't
this leads to one of the major confusions in the omap_hsmmc driver
- platform data should be read-only for the driver
most callbacks are not set by the omap3 platform init code while still
required. So they are set from the driver probe function, which is against
the paradigm that platform-data should not be modified by the driver
typical examples are card_detect, read_only callbacks
un-bundling by searching for driver name \"omap_hsmmc in the
arch/arm folder. omap_hsmmc_platform_data is not initialized directly,
but from omap2_hsmmc_info, which is defined in a separate header file
not touched by this patch
hwmod includes platform headers to declare features of the platform. All
the declared features are prefixed OMAP_HSMMC. There is no need to
include platform header from hwmod other except for feature defines

Only a few files really need that platform header. When later splitting
omap_mmc_platform_data into omap_mmc and omap_mmc_hs, those files

Without this, the USB devices are sometimes not detected on OMAP4 Panda
with u-boot v2013.10.
Unlike what the comment states, errata i660 does not state that we
can't RESET the USB host module. Instead it states that RESET is the
only way to recover from a deadlock situation.
RESET ensures that the module is in a known good state irrespective
of what bootloader does with the module, so it must be done at boot.

For modules/IPs/hwmods which do not have
-1- sys->class->reset()
and
-2- hardreset lines
and
-3- No way to do an ocp reset (no sysc control)
the flag 'HWMOD_INIT_NO_RESET' is not much useful.
Cleanup all such instances across various hwmod data files.

With commit '82702ea11ddfe0e43382e1fa5b66d807d8114916' "ARM: OMAP2+:
Fix serial init for device tree based booting" stubbing out
omap_serial_early_init() for Device tree based booting, there was a
crash observed on AM335x based devices when hwmod does a
_setup_reset() early at boot.
This was rootcaused to hwmod trying to reset console uart while
earlycon was using it. The way to tell hwmod not to do this is to
specify the HWMOD_INIT_NO_RESET flag, which were infact set by the
omap_serial_early_init() function by parsing the cmdline to identify
the console device.
Parsing the cmdline to identify the uart used by earlycon itself seems
broken as there is nothing preventing earlycon to use a different one.
This patch, instead, attempts to populate the requiste flags for hwmod
based on the CONFIG_DEBUG_OMAPxUARTy FLAGS. This gets rid of the need
for cmdline parsing in the DT as well as non-DT cases to identify the
uart used by earlycon.

Commit '3b9b10151c6838af52244cec4af41a938bb5b7ec' cleaned up the
data file to remove all irq and dma entries for all hwmods, which
are now populated by DT. But mcspi and mmc irq, dma entries were
retained since MMC, NFS boot was not working. Since it is root caused
to be an issue with only DMA entries [1], irq can be safely removed.

Commit 3b9b10151c6838af52244cec4af41a938bb5b7ec (ARM: OMAP4: hwmod data:
Clean up the data file) removes hwmod data for omap4, including DSS
data. DSS has not yet been converted to DT, so the hwmod data is still
needed.
This patch adds back the DSS parts of the hwmod data.
