Subject: [PATCH 1/3] clk: qcom: gcc-sm6115: Override default Alpha PLL regs
From: Adam Skladowski <a_skl39@...tonmail.com>
The DEFAULT and BRAMMO PLL offsets are non-standard in downstream, but
currently only BRAMMO ones are overridden. Override DEFAULT ones too.
A very similar thing is happening in gcc-qcm2290 driver.
Fixes: cbe63bfdc54f ("clk: qcom: Add Global Clock controller (GCC) driver for SM6115")
