Subject: [RESEND PATCH v2 03/13] clk: qcom: clk-alpha-pll: same regs and ops for trion and lucid
Date: Mon, 29 Jun 2020 17:17:09 -0400	[thread overview]
Message-ID: <20200629211725.2592-4-jonathan@marek.ca> (raw)
In-Reply-To: <20200629211725.2592-1-jonathan@marek.ca>

Fixed ops were already identical, this adds support for non-fixed ops by
sharing between trion and lucid.

This also changes the names for trion ops to be consistent with the rest.

Note LUCID_PCAL_DONE is renamed to TRION_PCAL_DONE because it is wrong for
lucid, LUCID_PCAL_DONE should be BIT(27). Next patch will address this.

Signed-off-by: Jonathan Marek <jonathan@marek.ca>
