This patch can be discarded,.After adding this series https://lore.kernel.org/r/20230523193017.4109557-1-dianders@chromium.org， Thanks! I'll see if I can give that series a spin soon and then see how we can make progress to getting it landed. > using ekth6915 also can meet my needs. Even if using ekth6915 can meet your needs, it's still better to actually add the right compatible string. Putting in the device tree that you have an "elan6915" and that you're providing "vcc33" isn't the best when you actually have a different touchscreen and are providing a very different voltage. Adding the proper bindings is definitely preferred. > On Wed, May 31, 2023 at 12:58 AM Doug Anderson <dianders@chromium.org> wrote: >> >> Hi, >> >> On Tue, May 30, 2023 at 4:56 AM Krzysztof Kozlowski <krzk@kernel.org> wrote: >> > >> > On 22/05/2023 17:33, Doug Anderson wrote: >> > > Hi, >> > > >> > > On Fri, May 19, 2023 at 10:07 PM Cong Yang >> > > <yangcong5@huaqin.corp-partner.google.com> wrote: >> > >> >> > >> Add an ilitek touch screen chip ili9882t. >> > >> >> > >> Signed-off-by: Cong Yang <yangcong5@huaqin.corp-partner.google.com> >> > >> --- >> > >> .../devicetree/bindings/input/elan,ekth6915.yaml | 9 +++++++-- >> > >> 1 file changed, 7 insertions(+), 2 deletions(-) >> > > >> > > I'm curious about the DT maintainers opinion here.
