2019-11-21video: hyperv: hyperv_fb: Support deferred IO for Hyper-V frame buffer driverWei Hu2-21/+190
Without deferred IO support, hyperv_fb driver informs the host to refresh the entire guest frame buffer at fixed rate, e.g. at 20Hz, no matter there is screen update or not. This patch supports deferred IO for screens in graphics mode and also enables the frame buffer on-demand refresh. The highest refresh rate is still set at 20Hz. Currently Hyper-V only takes a physical address from guest as the starting address of frame buffer. This implies the guest must allocate contiguous physical memory for frame buffer. In addition, Hyper-V Gen 2 VMs only accept address from MMIO region as frame buffer address. Due to these limitations on Hyper-V host, we keep a shadow copy of frame buffer in the guest. This means one more copy of the dirty rectangle inside guest when doing the on-demand refresh. This can be optimized in the future with help from host. For now the host performance gain from deferred IO outweighs the shadow copy impact in the guest.

2019-11-11backlight: gpio: Explicitly set the direction of the GPIOBartosz Golaszewski1-5/+18
The GPIO backlight driver currently requests the line 'as is', without acively setting its direction. This can lead to problems: if the line is in input mode by default, we won't be able to drive it later when updating the status and also reading its initial value doesn't make sense for backlight setting. Request the line 'as is' initially, so that we can read its value without affecting it but then change the direction to output explicitly when setting the initial brightness. Also: check the current direction and only read the value if it's output.

2019-11-01backlight: qcom-wled: Add auto string detection logicKiran Gunda1-6/+394
The auto string detection algorithm checks if the current WLED sink configuration is valid. It tries enabling every sink and checks if the OVP fault is observed. Based on this information it detects and enables the valid sink configuration. Auto calibration will be triggered when the OVP fault interrupts are seen frequently thereby it tries to fix the sink configuration. The auto-detection also kicks in when the connected LED string of the display-backlight malfunctions (because of damage) and requires the damaged string to be turned off to prevent the complete panel and/or board from being damaged.

2019-10-14backlight: pwm_bl: Switch to power-of-2 base for fixed-point mathRasmus Villemoes1-10/+12
Using a power-of-2 instead of power-of-10 base makes the computations much cheaper. 2^16 is safe; retval never becomes more than 2^48 + 2^32/2. On a 32 bit platform, the very expensive 64/32 division at the end of cie1931() instead becomes essentially free (a shift by 32 is just a register rename).

For a fixed small exponent of 3, it is more efficient to simply use two explicit multiplications rather than calling the int_pow() library function: Aside from the function call overhead, its implementation using repeated squaring means it ends up doing four 64x64 multiplications.
