Subject: [PATCH v3 3/5] pinctrl: qcom: Move chip specific functions to right files
Date: Mon, 29 Nov 2021 15:28:50 +0530 [thread overview]
Message-ID: <1638179932-3353-4-git-send-email-srivasam@codeaurora.org> (raw)
In-Reply-To: <1638179932-3353-1-git-send-email-srivasam@codeaurora.org>
Update lpass lpi pin control driver to accommodate new lpass variant
SoC specific drivers.
Move sm8250 SoC specific functions to pinctrl-sm8250-lpass-lpi.c file
and common declarations to pinctrl-lpass-lpi.h header file.

Subject: [PATCH v3 3/5] pinctrl: qcom: Move chip specific functions to right files
Date: Mon, 29 Nov 2021 15:28:50 +0530 [thread overview]
Message-ID: <1638179932-3353-4-git-send-email-srivasam@codeaurora.org> (raw)
In-Reply-To: <1638179932-3353-1-git-send-email-srivasam@codeaurora.org>
Update lpass lpi pin control driver to accommodate new lpass variant
SoC specific drivers.
Move sm8250 SoC specific functions to pinctrl-sm8250-lpass-lpi.c file
and common declarations to pinctrl-lpass-lpi.h header file.
