This will be used by a number of planned drivers including a new USB PHY driver and common clock framework drivers. The same defines are removed from the platform_data header file since they are now redundant and they didn't really belong there anyway. Signed-off-by: David Lechner --- v3 changes: This is a new patch. It replaces the previous patch that just added some missing CFGCHIP2 registers to the platform_data/usb-davinci.h file. I took David Laight's advice and included all of the possible registers. Many of these registers will be used for clocks - hopefully in the near future. include/linux/mfd/da8xx-cfgchip.h | 160 ++++++++++++++++++++++++++++++ include/linux/platform_data/usb-davinci.h | 23 ----- 2 files changed, 160 insertions(+), 23 deletions(-) create mode 100644 include/linux/mfd/da8xx-cfgchip.h diff --git a/include/linux/mfd/da8xx-cfgchip.h b/include/linux/mfd/da8xx-cfgchip.h new file mode 100644 index 0000000..6940cf9 --- /dev/null +++ b/include/linux/mfd/da8xx-cfgchip.h @@ -0,0 +1,160 @@ +/* + * TI DaVinci DA8xx CHIPCFGx registers for syscon consumers. + * + * Copyright (C) 2016 David Lechner + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
