[PATCH v3 0/3] HSI2 support for Google Tensor gs101

From: André Draszik
Date: Mon Apr 29 2024 - 09:05:56 EST


This patch series enables the HSI2 (high speed interfaces) for gs101:

- HSI2 feeds PCIe and UFS

The parts added here have been verified to work OK without the
clk_ignore_unused kernel command line option.

Changes in v3:
- Drop HSI0-related changes as already applied
- s/ufs_embd/ufs and s/mmc_card/mmc (Tudor, Krzysztof)
- collect tags
- drop my own R-b tag, due to SoB
- Link to v2: https://lore.kernel.org/r/20240426-hsi0-gs101-v2-0-2157da8b63e3@xxxxxxxxxx

Changes in v2:
- My v1 just contained HSI0, but due due to changing similar areas in the
code, I've also added Peter's HSI2 clock patches from
https://lore.kernel.org/all/20240423205006.1785138-1-peter.griffin@xxxxxxxxxx
to this series so as to preempt any merge conflicts. Namely:
* hsi2 bindings
* hsi2 DT
* hsi2 cmu clock driver
- drop patch 'dt-bindings: clock: google,gs101-clock: add HSI0 clock
management unit' as already applied
- cometic updates to patch 4: 'clk: samsung: gs101: add support for
cmu_hsi0' (macro name, a whitespace, subject line)
- Link to v1: https://lore.kernel.org/r/20240423-hsi0-gs101-v1-0-2c3ddb50c720@xxxxxxxxxx
