2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2019-02-09mmc: tmio: Make DMA transfer end bit configurableMarek Vasut
Different versions of the SDHI core use either bit 17 or bit 20 for the DTRAEND indication, which can differ even between SoC revisions. Make the DTRAEND bit position part of the driver private data, so that the probe function can set this accordingly. Set this to 20 on Socionext SoCs and either 17 or 20 on Renesas SoCs, depending on the SoC.

2018-12-03mmc: tmio: Switch to clock frameworkMarek Vasut
Switch the driver to using clk_get_rate()/clk_set_rate() instead of caching the mclk frequency in it's private data. This is required on the SDHI variant of the controller, where the upstream mclk need to be adjusted when using UHS modes. Platforms which do not support clock framework or do not support it in eg. SPL default to 100 MHz clock. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Masahiro Yamada <yamada.masahiro@socionext.com> --- V2: - Fix build on certain platforms using SPL without clock framework V3: - Turn clk_get_rate into a callback and fill it as needed on both renesas and socionext platforms

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-24mmc: uniphier-sd: skip clock set-up for SPLMasahiro Yamada
The size of SPL is hitting the limit (64KB) for uniphier_v7_defconfig. When booting from SD/eMMC, obviously its clock has been properly set up by the boot ROM. Acutually, no need to re-initialize the clock in SPL. Using a clock driver would generalize the SoC specific code, but solving the memory footprint problem would win.

2018-04-24mmc: tmio: move clk_enable() to each driver's probe functionMasahiro Yamada
I need to differentiate the clock handling for uniphier-sd. Move it to each driver's probe function from the tmio common code so that renesas-sdhi will not be affected. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2018-04-11mmc: uniphier: Allow passing quirks to the probe functionMarek Vasut

2018-04-11mmc: uniphier: Split out SoC specific bits from the driverMarek Vasut
Factor out common code from the uniphier SD driver, change the prefix of the functions from uniphier_sd_ to matsu_sd_ and create separate renesas-sdhi.c driver. Thus far, all the code is still compiled when CONFIG_UNIPHIER_MMC is selected and there is no functional change. This patch is a preparation for further split of the SoC specific parts of the Matsushita SD driver, used both on Uniphier and R-Car.

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.

2016-06-19clk: convert API to match reset/mailbox styleStephen Warren
The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).
