On Pixel 6 (and Pro), a max77759 companion PMIC for USB Type-C applications is used, which contains four functional blocks (at distinct I2C addresses): * top (including GPIO) * charger * fuel gauge * TCPCi While in the same package, TCPCi and Fuel Gauge have separate I2C addresses, interrupt lines and interrupt status registers and can be treated independently. The TCPCi is required to detect and handle connector orientation in Pixel's USB PHY driver, and to configure the USB controller's role (host vs device). This change adds the TCPCi part as it can be independent and doesn't need a top-level MFD. Signed-off-by: André Draszik <andre.draszik@linaro.org> --- v2: * compatible has changed to maxim,max77759-tcpci * clarify that GPIO is actually part of 'top' in commit message, not separate --- arch/arm64/boot/dts/exynos/google/gs101-oriole.dts | 99 ++++++++++++++++++++++ 1 file changed, 99 insertions(+)
