2018-01-19drivers: dma: ti-edma3: add support for memory fillTero Kristo
Add support for simple memory fill operation. With large data sizes it is much faster to use EDMA for memory fill rather than CPU. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory. The semantic patch I used is as follows: // <smpl> @@@@ -error +pr_err (...) // </smpl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org> [trini: Re-run Coccinelle] Signed-off-by: Tom Rini <trini@konsulko.com>
2017-06-01dm: Rename dev_addr..() functionsSimon Glass
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

2017-06-01dm: Use dm.h header when driver mode is usedSimon Glass
This header includes things that are needed to make driver build. Adjust existing users to include that always, even if other dm/ includes are present Signed-off-by: Simon Glass <sjg@chromium.org>

2014-10-23dma: ti-edma3: introduce edma3 driverKhoronzhuk, Ivan
The EDMA3 controller’s primary purpose is to service data transfers that you program between two memory-mapped slave endpoints on the device. Typical usage includes, but is not limited to the following: - Servicing software-driven paging transfers (e.g., transfers from external memory, such as SDRAM to internal device memory, such as DSP L2 SRAM) - Servicing event-driven peripherals, such as a serial port - Performing sorting or sub-frame extraction of various data structures - Offloading data transfers from the main device DSP(s) - See the device-specific data manual for specific peripherals that are accessible via the EDMA3 controller Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>
