Subject: [PATCH v8 05/42] clk: davinci: Add platform information for TI DM355 PLL
Date: Thu, 15 Mar 2018 21:52:21 -0500	[thread overview]
Message-ID: <1521168778-27236-6-git-send-email-david@lechnology.com> (raw)
In-Reply-To: <1521168778-27236-1-git-send-email-david@lechnology.com>

This adds platform-specific declarations for the PLL clocks on TI
DM355 based systems.

Signed-off-by: David Lechner <david@lechnology.com>
---

v8 changes:
- drop __init and __initconst attributes
- add a clkdev lookup for each SYSCLK

v7 changes:
- split registration functions for each PLL
- Add platform_device_id lookup

v6 changes:
- Added dm355_pll{1,2}_info with controller-specific information
- Add empty lines between function calls
