Subject: [PATCH v2 00/10] pmdomain: samsung: add supoort for Google GS101

Hi,

This series adds support for the power domains on Google GS101. It's
fairly similar to SoCs already supported by this driver, except that
register acces does not work via plain ioremap() / readl() / writel().
Instead, the regmap created by the PMU driver must be used (which uses
Arm SMCC calls under the hood).

The DT update to add the new required properties on gs101 will be
posted separately.
