2022-07-19drm/panel/panel-sitronix-st7701: Adjust porch control bitfield nameMarek Vasut1-4/+6
Define DSI_CMD2_BK0_PORCTRL_VBP_MASK and DSI_CMD2_BK0_PORCTRL_VFP_MASK and move the vertical back and front porch calculation from macros into the st7701_init_sequence() function, so it is clear what this does.

2022-07-19drm/panel/panel-sitronix-st7701: Infer vertical line count from TFT modeMarek Vasut1-6/+20
The vertical line count is a property of the TFT matrix. Currently the driver hard-codes content of this register to specific value which is only compatible with one TFT matrix, likely the TS8550B one. Calculate the vertical line count from the mode instead.

The gamma correction values are specific to the TFT which is attached to the ST7701 TFT matrix driver, move the gamma correction values from what incorrectly looks like common init sequence into TFT matrix specific settings. While doing so, add macros which defined fields within the gamma register file and a macro which mimics FIELD_PREP except works with constant expressions.

The ST7701(S) is capable of DSI burst mode, which is more energy efficient than the non-burst modes. Make use of it. The ST7701(S) is capable of DSI non-continuous clock, since it sources the TFT matrix driver clock from internal clock source. The DSI non-continuous clock further reduce power utilization. The ST7701(S) uses DSI LPM for command transmissions, make sure this is configured correctly in the DSI mode flags.

2022-07-19drm/panel/panel-sitronix-st7701: Make DSI mode flags common to ST7701Marek Vasut1-3/+1
The ST7701 and ST7701S are TFT matrix drivers with integrated multi protocol decoder capable of DSI/DPI/SPI input and 480x360...864 line TFT matrix output. Currently the only supported input is DSI. The protocol decoder is separate from the TFT matrix driver and is always capable of handling all of DSI non-burst mode with sync pulses or sync events as well as DSI burst mode. Move the DSI mode configuration from TFT matrix driver properties to common ST7701 code, because this is common to all TFT matrices.

2022-07-19gpiolib: cdev: consolidate edge detector configuration flagsKent Gibson1-66/+60
Combine the polarity_change flag, struct line eflags, and hte enable flag into a single flag variable. The combination of these flags describes the configuration state of the edge detector, so formalize and clarify that by combining them into a single variable, edflags, in struct line. The edflags is a subset of the GPIO_V2_LINE_FLAGsb relevant to the edge detector, and is also a superset of the eflags it replaces. The eflags name is still used to describe the subset of edflags corresponding to the rising/falling edge flags where edflags is masked down to that subset. This consolidation reduces the number of variables being passed, simplifies state comparisons, and provides a more extensible foundation should additional edge sources be integrated in the future.

We should use of_node_get() when a new reference of device_node is created. It is noted that the old reference stored in 'mm_gc->gc.of_node' should also be decreased. This patch is based on the fact that there is a call site in function 'qe_add_gpiochips()' of src file 'drivers\soc\fsl\qe\gpio.c'. In this function, of_mm_gpiochip_add_data() is contained in an iteration of for_each_compatible_node() which will automatically increase and decrease the refcount. So we need additional of_node_get() for the reference escape in of_mm_gpiochip_add_data().

2022-07-19dt-bindings: gpio: gpio-mvebu: document offset and marvell,pwm-offsetChris Packham1-0/+8
The offset and marvell,pwm-offset properties weren't in the old binding. Add them based on the existing usage in the driver and board DTS when the marvell,armada-8k-gpio compatible is used.

2022-07-19dt-bindings: gpio: gpio-mvebu: deprecate armadaxp-gpioChris Packham1-16/+8
Commit 5f79c651e81e ("arm: mvebu: use global interrupts for GPIOs on Armada XP") the marvell,armadaxp-gpio compatible obsolete. The driver code still exists to handle the armadaxp behaviour but all the in-tree boards use the marvell,armada-370-gpio. Document the marvell,armadaxp-gpio compatible as deprecated.

2022-07-19dt-bindings: gpio: gpio-mvebu: convert txt binding to DT schema formatChris Packham5-96/+149
Convert the existing device tree binding to DT schema format. The old binding listed the interrupt-controller and related properties as required but there are sufficiently many existing usages without it that the YAML binding does not make the interrupt properties required.
