Subject: [PATCH v2 0/4] hook up pin controller clocks on Google Tensor gs101
Date: Tue, 30 Apr 2024 10:49:45 +0100 [thread overview]
Message-ID: <20240430-samsung-pinctrl-busclock-dts-v2-0-14fc988139dd@linaro.org> (raw)
This series hooks up the individual clocks for each pin controller in the
gs101 DTS.
On Google Tensor gs101 there are separate bus clocks / gates each for each
pinctrl instance. To be able to access each pinctrl instance's registers,
this bus clock needs to be running, otherwise register access will hang.
The driver update to support this extra clock has been proposed in
https://lore.kernel.org/r/20240426-samsung-pinctrl-busclock-v3-0-adb8664b8a7e@linaro.org
This series depends on:
* hsi2 series:
https://lore.kernel.org/r/20240429-hsi0-gs101-v3-0-f233be0a2455@linaro.org
* pin controller clock support:

Changes in v2:
- use <0> instead of a placeholder clock (Krzysztof)
- Link to v1: https://lore.kernel.org/r/20240429-samsung-pinctrl-busclock-dts-v1-0-5e935179f3ca@linaro.org
