Subject: Re: [PATCH v2 00/14] Add DRM driver for Solomon SSD16xx e-paper display controllers
Date: Fri,  2 Oct 2026 16:56:39 +0800	[thread overview]
Message-ID: <20261002085639.109873-1-zaq14760@gmail.com> (raw)
In-Reply-To: <20260927182329.4193961-1-devarsht@ti.com>

Hi Devarsh,

Setup: Raspberry Pi 5, rpi-7.2.y with your patches 01-12/14 cherry-picked
and the panel entry added locally, SPI0 CE0 at 5 and 20 MHz, DC/RST/BUSY
on GPIO5/6/26, CONFIG_DRM_SSD16XX=y, drm.debug=0x02, no compositor.

Bring-up is clean: it probes, the connector comes up at 800x480, and
reset/BUSY and runtime PM all work.  The three issues I reported on
31 July [1] are all gone - the mirroring is fixed by 11/14 [2], rotation
180 draws, and refresh_mode takes effect.

All four DT rotation values work, and so do the plane properties -
refresh_mode, color_mode, clear_on_init/close/disable and
refresh_mode_init.  SPI is fine at both 5 and 20 MHz.

Tested-by: LiangCheng Wang <zaq14760@gmail.com>
