2021-05-08trogdor: Add backlight support for sn65dsi86bridge for HomestarVinod Polimera
Add backlight support in sn65dsi86bridge through the AUX channel using eDP DPCD registers, which is needed on the GOOGLE_HOMESTAR board.

2021-05-08drivers/sn65dsi86: Switch EDID reading to use "indirect mode"Julius Werner
The SN65DSI86 eDP bridge supports two ways to read the EDID: for now we've been using "direct mode", which works by basically making the bridge I2C device listen to another chip address besides its own and proxy all requests received there directly to the eDP AUX channel. The great part about that mode is that it is super easy and hassle-free to use. The not so great part about it is that it doesn't work: for EDID extensions, the last byte (which happens to contain the checksum) is somehow always read as zero. We presume this is a hardware bug in the bridge part. The other, much more annoying way is "indirect mode", where each byte transmitted over the AUX channel has to be manually set up in the I2C registers of the bridge, just like we're already doing with DPCD transactions. Thankfully, we can reuse most of the DPCD code for this so it's not a lot of extra code. It's a bit slower but not as much as you'd expect (26ms instead of 18ms on my board), and the difference is not very relevant compared to common total times for display init. Also, some of the (previously unused) enum definitions for the AUX_CMD mode field of the bridge had just been plain wrong for some reason, and needed to be fixed to make this work.

DP link rates are reported in an array of LE16 values. The current code tries to parse them as 8-bit which doesn't get very far, causing us to always drop into the fallback path.

2020-10-09sc7180: Remove the delay to force hpd detection and always disable HPDVinod Polimera
HPD on this bridge chip is a bit useless. This is an eDP bridge so the HPD is an internal signal that's only there to signal that the panel is done powering up. But the bridge chip debounces this signal by between 100 ms and 400 ms (depending on process, voltage, and temperate). One particular panel asserted HPD 84 ms after it was powered on meaning that we saw HPD 284 ms after power on. Assume that the panel driver will have the hardcoded delay in its prepare and always disable HPD.

2014-12-16i2c: Replace the i2c API.Gabe Black
The new API is in use in depthcharge and is based around the "i2c_transfer" function instead of i2c_read and i2c_write. The new function takes an array of i2c_seg structures which represent each portion of the transfer after a start bit and before the stop bit. If there's more than one segment, they're seperated by repeated starts. Some wrapper functions have also been added which make certain common operations easy. These include reading or writing a byte from a register or reading or writing a blob of raw data. The i2c device drivers generally use these wrappers but can call the i2c_transfer function directly if the need something different. The tegra i2c driver was very similar to the one in depthcharge and was simple to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and replace the ones in coreboot. The Exynos 5420 driver was ported from the high speed portion of the one in coreboot and was straightforward to port back. The low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot and were replaced with the depthcharge implementation. BUG=None TEST=Built and booted on nyan with and without EFS.
