Subject: [PATCH v6 01/24] mfd: Add ingenic-tcu.h header
Date: Thu,  9 Aug 2018 23:43:51 +0200	[thread overview]
Message-ID: <20180809214414.20905-2-paul@crapouillou.net> (raw)
In-Reply-To: <20180809214414.20905-1-paul@crapouillou.net>

This header contains macros for the registers that are present in the
regmap shared by all the drivers related to the TCU (Timer Counter Unit)
of the Ingenic JZ47xx SoCs.

 create mode 100644 include/linux/mfd/ingenic-tcu.h

 v2: Use SPDX identifier for the license

 v3: - Use macros instead of enum
     - Add 'TCU_' at the beginning of each macro
	 - Remove useless include <linux/regmap.h>

 v4: No change

 v5: No change

 v6: Rename barrier macro from __LINUX_CLK_INGENIC_TCU_H__ to
     __LINUX_MFD_INGENIC_TCU_H__
