Subject: [RFT v2 01/10] pinctrl: samsung: Define suspend and resume callbacks for all banks and SoCs
Date: Mon, 23 Jul 2018 19:52:53 +0200 [thread overview]
Message-ID: <20180723175302.22535-2-krzk@kernel.org> (raw)
In-Reply-To: <20180723175302.22535-1-krzk@kernel.org>
Suspend and resume callbacks in Exynos/S5Pv210 pin controller drivers,
save and restore state of registers. This operations should be done for
all banks which have external interrupts (as denoted by using
EXYNOS_PIN_BANK_EINTG/EINTW macros).
Add all banks of Exynos5260 and Exynos5420. This is necessary step for
supporting suspend to RAM on these SoCs.
