[ Upstream commit feedaacdadfc332e1a6e436f3adfbc67e244db47 ]
This driver uses GPIO descriptors to drive the touchscreen RESET line. In
the existing device trees this has in conflict with intution been flagged
as GPIO_ACTIVE_HIGH and the driver then applies the reverse action by
driving the line low (setting to 0) to enter reset state and driving the
line high (setting to 1) to get out of reset state.
The correct way to handle active low GPIO lines is to provide the
GPIO_ACTIVE_LOW in the device tree (thus properly describing the hardware)
and letting the GPIO framework invert the assertion (driving high) to a
low level and vice versa.
This is considered a bug since the device trees are incorrectly
mis-specifying the line as active high.
Fix the driver and all device trees specifying a reset line.

Meraki MR26 is an EOL wireless access point featuring a
PoE ethernet port and two dual-band 3x3 MIMO 802.11n
radios and 1x1 dual-band WIFI dedicated to scanning.
Thank you Amir for the unit and PSU.
Hardware info:
SOC : Broadcom BCM53015A1KFEBG (dual-core Cortex-A9 CPU at 800 MHz)

MISC : Atmel AT24C64 8KiB EEPROM i2c
: Ti INA219 26V, 12-bit, i2c output current/voltage/power monitor
SERIAL:
WARNING: The serial port needs a TTL/RS-232 3V3 level converter!
The Serial setting is 115200-8-N-1. The board has a populated
right angle 1x4 0.1" pinheader.
The pinout is: VCC (next to J3, has the pin 1 indicator), RX, TX, GND.
Odd stuff:
- uboot does not support lzma compression, but gzip'd uImage/DTB work.
- uboot claims to support FIT, but fails to pass the DTB to the kernel.
Appending the dtb after the kernel image works.
- RGB-controller is supported through an external userspace program.
- The ubi partition contains a "board-config" volume. It stores the
MAC Address (0x66 in binary) and Serial No. (0x7c alpha-numerical).
- SoC's temperature sensor always reports that it is on fire.
This causes the system to immediately shutdown! Looking at reported
"418 degree Celsius" suggests that this sensor is not working.
WIFI:
b43 is able to initialize all three WIFIs @ 802.11bg.

commit 93a8ba2a619816d631bd69e9ce2172b4d7a481b8 upstream.
Contrary to what was believed at the time, the ramp delay of 150us is not
plenty for the PU LDO with the default step time of 512 pulses of the 24MHz
clock. Measurements have shown that after enabling the LDO the voltage on
VDDPU_CAP jumps to ~750mV in the first step and after that the regulator
executes the normal ramp up as defined by the step size control.
This means it takes the regulator between 360us and 370us to ramp up to
the nominal 1.15V voltage for this power domain. With the old setting of
the ramp delay the power up of the PU GPC domain would happen in the middle
of the regulator ramp with the voltage being at around 900mV. Apparently
this was enough for most units to properly power up the peripherals in the
domain and execute the reset. Some units however, fail to power up properly,
especially when the chip is at a low temperature. In that case any access
to the GPU registers would yield an incorrect result with no way to recover
from this situation.
Change the ramp delay to 380us to cover the measured ramp up time with a
bit of additional slack.
