Subject: ARM: OMAP: zoom: Use pwm stack for lcd and keyboard backlight

Use pwm_leds driver for the keyboard light and pwm-backlight for the lcd
backlight control (instead of implementing the PWM driver part in the board
file).

Add the gpio information to generic dpi panel's platform data so that it's

Note: Only BL enable gpio is handled in the panel driver. The LCD enable
GPIO is handled in the board file at init time, as there's a 50 ms delay
required when using the GPIO, and the panel driver doesn't know about
that.

Subject: arm: omap: board-am3517: use generic dpi panel's gpio handling

The am3517 board file currently requests gpios required to configure the sharp
lq DPI panel, and provides platform_enable/disable callbacks to configure them.

These tasks have been moved to the generic dpi panel driver itself and shouldn't
be done in the board files.

Remove the gpio requests and the platform callbacks from the board file.
Add the gpio information to generic dpi panel's platform data so that it's
passed to the panel driver.

Note: It's not clear why the GPIOs were muxed as input signals in PULL down mode
in am3517_evm_display_init(). Also, only the LCD_PANEL_PWR was toggled in the
platform_enable/disable calls, the generic DPI panel driver will now toggle all
the three gpios on panel's disable/enable. We need to test if these changes to
see if they have any impact or not.

Subject: arm: omap: board-ldp: use generic dpi panel's gpio handling

The ldp board file currently requests gpios required to configure the NEC DPI
panel, and provides platform_enable/disable callbacks to configure them.

These tasks have been moved to the generic dpi panel driver itself and shouldn't
be done in the board files.

Remove the gpio requests and the platform callbacks from the board file.
Configure the gpio information in generic dpi panel's platform data so that it's
passed to the panel driver.

Subject: arm: omap: board-overo: use lb035q02 dpi panel's gpio handling

The overo board file currently requests gpios required by the lb035q02 panel,
and provides platform_enable/disable callbacks to configure them.

These tasks have been moved to the lb035q02 dpi panel driver itself and should
be removed from the board files.

The lb035q02 panel driver uses generic dpi panel's platform data struct
internally. Remove the gpio requests and the platform callbacks from the board
file. Add the gpio information to the generic dpi panel platform data struct so
that it's passed to the panel driver.

Note: The GPIOs OMAP3EVM_LCD_PANEL_ENVDD and OMAP3EVM_LCD_PANEL_BKLIGHT_GPIO
aren't directly connected to the sharp panel, hence they aren't passed to the
panel driver as platform data. These are set to a default value such that LCD
is enabled and backlight is on. These used to previously toggle through the
platform_enable/disable callbacks, but now these are always on. This needs to
be revisited.

panel, and provides platform_enable/disable callbacks to configure them.

These tasks have been moved to the sharp_ls panel driver itself and shouldn't

Add the gpio information to panel_sharp_ls037v7dw01_data so that it's
passed to the panel driver.

Out of sharp panel's configurable pins, all apart from resb_gpio are managed by
a CPLD on the display and set to a default value. Only the configurable pin is
passed to platform data.

The backlight GPIO doesn't go directly to the sharp panel, it is used to set up
a voltage supply which goes to the LED+ pin of the panel, hence it isn't passed
to panel as platform data, and configured in the board file itself. The
backlight used to previously toggle through the platform_enable/disable
callbacks, but now it is always on. This needs to be revisited.

be done in the board files.

Remove the gpio requests and the platform callbacks from the board file. Pass
the panel_acx565akm_data instance 'lcd_data' to omap_dss_device instead of
passing the gpio number in omap_dss_device's reset_gpio.

Add the gpio information to panel_acx565akm_data so that it's passed to the
panel driver.

Subject: arm: omap: board-zoom: use NEC panel's gpio handling

The zoom board file currently requests gpios required by the nec-nl8048hl11-01
dpi panel, and provides dummy platform_enable/disable callbacks.

gpio request and configuration have been moved to the nec-nl8048hl11-01 panel
driver itself and shouldn't be done in the board files.

Remove the gpio requests and the platform callbacks from the board file. Add the
gpio information to panel_nec_nl8048_data so that it's passed to the panel
driver.

Subject: arm: omap: dss-common: use picodlp panel's gpio handling

The dss-common file currently requests gpios required by the picodlp DPI
panel on the 4430sdp/blaze board. It also requests DISPLAY_SEL_GPIO and
DLP_POWER_ON_GPIO gpios which are board specific gpios to switch between lcd2
panel and picodlp, and setting intermediate power supplies for picodlp
respectively. These gpios are toggled through platform_enable/disable functions
called by the picodlp driver.

Remove the gpio requests for the gpios which are already requested by the panel
driver, and remove the platform callback functions and set the platform specific
gpios in such a way that lcd2 panel is selected for the LCD2 overlay manager and
the power supplies for picodlp are disabled.

Note: We need to revisit this so that we can enable and switch to picodlp if
that's the only panel driver available for the LCD2 overlay manager.

Subject: ARM: convert arm/arm64 arch timer to use CLKSRC_OF init

This converts arm and arm64 to use CLKSRC_OF DT based initialization for
the arch timer. A new function arch_timer_arch_init is added to allow for
arch specific setup.

This has a side effect of enabling sched_clock on omap5 and exynos5. There
should not be any reason not to use the arch timers for sched_clock.

Subject: ARM: OMAP: remove unused variable

Commit 0583fe478a7 "ARM: convert arm/arm64 arch timer to use CLKSRC_OF init"
has left the omap5_realtime_timer_init() function with a stale variable and
broken whitespace. This fixes both.

Subject: ARM: OMAP2+: Fix mismerge for timer.c between ff931c82 and da4a686a

Looks like the timer.c fixes in commit ff931c82 (ARM: OMAP: clocks:
Delay clk inits atleast until slab is initialized) got lost in a
merge with da4a686a (ARM: smp_twd: convert to use CLKSRC_OF init).

Without the omap_clk_init() calls none of OMAP family of devices
boot.

Subject: ARM: OMAP4: change the device names in usb_bind_phy

After the device names are created using PLATFORM_DEVID_AUTO, the old
device names given in usb_bind_phy are no longer valid causing the musb
controller not to get the phy reference. Updated the usb_bind_phy with
the new device names to get MUSB functional in omap4 panda.
