ba3770416d DaVinci fixes for v5.4
======================
 * fix GPIO backlight support on DA850 by enabling the needed config
   in davinci_all_defconfig. This is a fix because the driver and board
   support got converted to use BACKLIGHT_GPIO driver, but defconfig update
   is still missing in v5.4.
 * fix for McBSP DMA on DM365

279296ed20 Fixes for omaps for v5.4-rc cycle
More fixes for omap variants:
 
 - Update more panel options in omap2plus_defconfig that got changed
   as we moved to use generic LCD panels
 
 - Remove unused twl_keypad for logicpd-torpedo-som to avoid boot
   time warnings. This is only a cosmetic fix, but at least dmesg output
   is now getting more readable after all the fixes to remove pointless
   warnings
 
 - Fix gpu_cm node name as we still have a non-standard node name
   dependency for clocks. This should eventually get fixed by use
   of domain specific compatible property
 
 - Fix use of i2c-mux-idle-disconnect for m3874-iceboard
 
 - Use level interrupt for omap4 & 5 wlcore to avoid lost edge
   interrupts

The commit e7774049ff ("ARM: dts: bcm283x: Define MMC interfaces at
board level") accidently dropped the bus width for the sdhci on the
RPi Zero W, because the board file was relying on the defaults
from bcm2835-rpi.dtsi. So fix this performance regression by adding
the bus width to the board file.

a9082575f8 arm64: dts: rockchip: Fix override mode for rk3399-kevin panel
When I re-posted Sean's original commit to add the override mode for
the kevin panel, for some reason I didn't notice that the pixel clock
wasn't quite right.  Looking at /sys/kernel/debug/clk/clk_summary on
downstream kernels it can be seen that the VOP clock is supposed to be
266,666,667 Hz achieved by dividing the 800 MHz PLL by 3.

Looking at history, it seems that even Sean's first patch [1] had this
funny clock rate.  I'm not sure where it came from since the commit
message specifically mentioned 26666 kHz and the Chrome OS tree [2]
can be seen to request 266667 kHz.

In any case, let's fix it up.  This together with my patch [3] to do
the proper rounding when setting the clock rate makes the VOP clock
more proper as seen in /sys/kernel/debug/clk/clk_summary.

087a2b7ec9 ARM: dts: Use level interrupt for omap4 & 5 wlcore
Commit 572cf7d7b0 ("ARM: dts: Improve omap l4per idling with wlcore edge
sensitive interrupt") changed wlcore interrupts to use edge interrupt based
on what's specified in the wl1835mod.pdf data sheet.

However, there are still cases where we can have lost interrupts as
described in omap_gpio_unidle(). And using a level interrupt instead of edge
interrupt helps as we avoid the check for untriggered GPIO interrupts in
omap_gpio_unidle().

And with commit e6818d29ea ("gpio: gpio-omap: configure edge detection
for level IRQs for idle wakeup") GPIOs idle just fine with level interrupts.

Let's change omap4 and 5 wlcore users back to using level interrupt
instead of edge interrupt. Let's not change the others as I've only seen
this on omap4 and 5, probably because the other SoCs don't have l4per idle
independent of the CPUs.

From the schematics a voltage range of 0.8V to 1.7V can be calculated.
Additional voltage measurements on the board show that this fix indeed
leads to the correct voltage, while without this fix the voltage was set
too high.

 - For omap3-gta04, gpio changes caused the LCD to break a while back,

 - Recent omapdrm and backlight changes also finally made droid4 LCD
   to work, so let's enable it in the defconfig it can be used out
   of the box. This is not strictly a fix, but we still also have the
   older CONFIG_MFD_TI_LMU options available so this cuts down the
   confusion for trying to guess which display and which backlight
   is needed
 
 - Recent ti-sysc interconnect target module changes need the gpio
   module disabled on some boards, but this now needs to happen at
   the module level, not at the gpio driver level
 
 - Recent changes to probe system timers with ti-sysc caused warnings
   about mismatch in syconfig registers, so let's configure the option
   for RESET_STATUS as available in the TRMs
 
 - Recent changes to probe LCDC with ti-sysc caused warnings about

   idlemodes for both platform data and dts as documented in TRMs
 
 - Since we moved mach-omap2 to probe with device tree, we've been
   getting voltage controller warnings. Turns out this code is no
   longer needed, so let's just remove omap2_set_init_voltage() to
   get rid of the pointless warnings
