Subject: [PATCH 12/15] clk: rockchip: rk3528: Fix trivial clock configuration errors
Date: Thu, 30 Jul 2026 14:13:01 +0000	[thread overview]
Message-ID: <20260730141308.1218014-13-jonas@kwiboo.se> (raw)
In-Reply-To: <20260730141308.1218014-1-jonas@kwiboo.se>

The RK3528 clock driver has a few trivial copy-paste mistakes in its
clock handling.

Fix the trivial clock configuration errors:
- avoid reporting incorrect PWM clock rate
- use correct mask and value for VOP clocks
- align PPLL configuration to match other PLLs
