[Intel-gfx] [PATCH 1/5] drm/i915/dsi: wait for header and payload credit available

[Lee Shawn C]

Driver should wait for free header or payload buffer in FIFO.
It would be good to wait a while for HW to release credit before
give it up to write to HW. Without sending initailize command
sets completely. It would caused MIPI display can't light up properly.

[Intel-gfx] [PATCH 2/5] drm/i915/dsi: refine send MIPI DCS command sequence

[Lee Shawn C]

According to chapter "Sending Commands to the Panel" in bspec #29738
and #49188. If driver try to send DCS long pakcet, we have to program
TX payload register at first. And configure TX header HW register later.
DSC long packet would not be sent properly if we don't follow this
sequence.

[Intel-gfx] [PATCH 3/5] drm/i915: Get proper min cdclk if vDSC enabled

[Lee Shawn C]

VDSC engine can process only 1 pixel per Cd clock. In case
VDSC is used and max slice count == 1, max supported pixel
clock should be 100% of CD clock. Then do min_cdclk and
pixel clock comparison to get proper min cdclk.

v2:
- Check for dsc enable and slice count ==1 then allow to
  double confirm min cdclk value.

[Intel-gfx] [PATCH 4/5] drm/i915/dsi: Retrieve max brightness level from VBT

[Lee Shawn C]

So far, DCS backlight driver hardcode (0xFF) for max brightness level.
MIPI DCS spec allow max 0xFFFF for set_display_brightness (51h) command.
And VBT brightness precision bits can support 8 ~ 16 bits.

We should set correct precision bits in VBT that meet panel's request.
Driver can refer to this setting then configure max brightness level
in DCS backlight driver properly.

v2: modify variable name brightness_precision_bits instead of
    max_brightness_level.

[Intel-gfx] [PATCH 5/5] drm/i915/dsi: Read/write proper brightness value via MIPI DCS command

[Lee Shawn C]

Driver has to swap the endian before send brightness level value
to tcon.

v2: Use __be16 instead of u16 to fix sparse warning.
v3: Send one or two bytes brightness value depend on the precision.

Unnecessary braces around the whole thing.

I think it's confusing to use __be16 in set and u8 data[2] in get. Let's
just use u8 data[2] in both. Especially because this one will always
write 0 for len == 1 as it's big-endian data!

You may have to do something like to keep it clear:

	size_t len = panel->backlight.max > U8_MAX ? 2 : 1;

	if (len == 1) {
		data[0] = level;
	} else {
		data[0] = level >> 8;
		data[1] = level;
	}
