Only ah needs to be set to 0 before calling interrupt 0x16 for waiting
for a keypress.
This patch changes the line that uses xor so that it only zeroes "ah" instead
of "ax".
This saves a byte.

i2c-mux instantiates one i2c_algorithm for each downstream adapter.
However these algorithms are all identical, depending only on the
parent adapter.
Avoid duplication by hoisting the i2c_algorithm from the adapters to
the i2c_mux_core object, and reuse it in all the adapters

This warning does not seem to be useful. Most of the time it fires when
allocation size depends on syscall arguments. We could add __GFP_NOWARN
to these allocation sites, but having a warning only to suppress it
does not make lots of sense. Moreover, this warnings never fires

This patch add support for Bananapi S070WV20-CT16 DSI panel to
BPI-M64 board.
DSI panel connected via board DSI port with,
- DC1SW as AVDD supply
- DCDC1 as DVDD supply
- PD6 gpio for reset pin
- PD5 gpio for backlight enable pin
- PD7 gpio for backlight vdd supply

The A64 has a MIPI-DSI block which is similar to A31
without mod clock.
So, add dsi node with A64 compatible, dphy node with
A31 compatible and finally connect dsi to tcon0 to
make proper DSI pipeline.

Accordingly to BPI-M64-bsp DE DSI code Video start delay
can be computed by subtracting total vertical timing with
front porch timing and with adding 1 delay line for TCON.
This patch simply add the start_delay logic from BPI-M64-bsp,
w/o this new computation, the DSI on A64 encounter vblank time
TCON DRQ set bits for non-burst DSI mode can computed via
horizontal front porch instead of front porch + sync timings.
Since there no documentation for TCON_DRQ_REG(0x7c) register
this change is taken as reference from BPI-M64-bsp.

According to horizontal and vertical timings are defined

Back porch = [hv]total - [hv]sync_end

This series add MIPI-DSI support on Allwinner A64. The same A31 controller
is reused and tweaked for A64 since the register space for both SoC's look same.
The current clock rate (270MHz) with nkm (5,2,11) from PLL_MIPI is unable to
work
with A64 DSI block. I've tested with few changes to verify
DSI DPHY gate bit on MIPI DSI clock register is bit 15
not bit 30.

The joystick (B3) on stm32746g-eval uses gpios on STMFX gpio expander.
These gpios need a pin configuration (push-pull and bias-pull-up),
described under stmfx_pinctrl node.
