* sunxi: Make DRAM_ODT_EN Kconfig setting a boolHans de Goede2015-05-19-2/+2
| | | | | | | | | | | | | | | | | Make DRAM_ODT_EN Kconfig setting a bool, add a separate DRAM_ODT_CORRECTION setting for A23 SoCs and use DRAM_ODT_EN Kconfig everywhere instead of only in dram_sun4i.c and hardcoding odt_en elsewhere. Note this commit makes no functional changes for existing boards, its purpose is to allow changing the odt_en value on future A33 boards. For sun4i/sun5i/sun7i boards which set DRAM_ODT_EN=y (which no defconfigs currently do) this patch turns on odt for both the DQ and the DQS lines, whereas previously it was possibly (but not desirable) to turn odt on only for one of them by setting the in DRAM_ODT_EN option to 1 or 2 instead of 3.

* sunxi: Move await_completion dram helper to dram.hHans de Goede2015-01-14-15/+2
| | | | | | | | | The await_completion helper is already copy pasted between the sun4i and sun6i dram code, and we need it for sun8i too, so lets make it an inline helper in dram.h, rather then adding yet another copy.

* sun4i: Rename dram_clk_cfg to dram_clk_gateHans de Goede2014-11-25-2/+2
| | | | | | | | | The data sheet just calls it DRAM_CLK_REG, and on sun6i we've both a dram_clk_cfg and dram_clk_gate, and the sun4i reg matches dram_clk_gate on sun6i, so name it the same on sun4i. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
