Subject: [PATCH v3 11/15] drm/mgag200: Move register initialization into separate function
Date: Fri, 15 May 2020 10:32:29 +0200	[thread overview]
Message-ID: <20200515083233.32036-12-tzimmermann@suse.de> (raw)
In-Reply-To: <20200515083233.32036-1-tzimmermann@suse.de>

Registers are initialized with constants. This is now done in
mgag200_init_regs(), mgag200_set_dac_regs() and mgag200_set_pci_regs().
Later patches should move these calls from mode setting to device
initialization.

v2:
	* replace uint8_t with u8
