Subject: [PATCH 5/9] arm64: dts: rockchip: Add the PHP GRF clock on RK3588
Date: Fri, 13 Nov 2026 16:38:51 +0000 [thread overview]
Message-ID: <20261113-mmu600-php-v1-5-231196049a3b@gmail.com> (raw)
In-Reply-To: <20261113-mmu600-php-v1-0-231196049a3b@gmail.com>
From: Arun Iyengar <aiyengar1990@gmail.com>
Once the PHP peripherals suspend, pclk_php_root is gated and a PHP GRF
access hangs; the syscore resume op of the next patch hung deep suspend
this way. Add the clock, so the syscon regmap enables it.
