* ARM: OMAP4/5: Move gpmc clocks to essential group.SRICHARAN R2012-07-07-2/+2
| | | | | | | | | | GPMC clocks are currently getting enabled as a part non-essential clocks. This will be required during NOR boot. Move this to essential group to keep the functionality, when non-essential clocks are not enabled. Signed-off-by: R Sricharan <r.sricharan@ti.com>
* ARM: OMAP4+: Move external phy initialisations to arch specific place.SRICHARAN R2012-07-07-27/+39
| | | | | | | | | | The external phy is present in the case OMAP5 soc is currently configured in emif-common.c. This results in having dummy structures for those Socs which do not have a external phy. So by having a weak function in emif-common and overriding it in OMAP5, avoids the use of dummy structures.

* omap4: Use a smaller M,N couple for IVA DPLLSebastien Jan2012-07-07-1/+1
| | | | | | | | | | This reduced M,N couple corresponds to the advised value from TI HW team. Tested on 4460 Pandaboard, it also provides peripheral clocks closer to the advised values. Signed-off-by: Sebastien Jan <s-jan@ti.com>
* da850/omap-l138: Enable auto negotiation in RMII modeRajashekhara, Sudhakar2012-07-07-0/+8
| | | | | | | | | | | | On DA850/OMAP-L138 it was observed that in RMII mode, auto negotiation was not performed. This patch enables auto negotiation in RMII mode. Without this patch, EMAC initialization takes more time and sometimes tftp fails in RMII mode.

* omap: am33xx: accomodate input clocks other than 24 MhzSteve Sakoman2012-07-07-5/+5

* omap: emif: fix bug in manufacturer code testSteve Sakoman2012-07-07-1/+1

* omap: emif: deal with rams that return duplicate mr data on all byte lanesSteve Sakoman2012-07-07-1/+6
| | | | | | | | | | Some rams (Micron for example) return duplicate mr data on all byte lanes. Users of the get_mr function currently don't deal with this duplicated data gracefully. This patch detects the duplicated data and returns only the expected 8 bit mr data. Signed-off-by: Steve Sakoman <steve@sakoman.com>
* OMAP4+: Force DDR in self-refresh after warm resetLokesh Vutla2012-07-07-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Errata ID:i727 Description: The refresh rate is programmed in the EMIF_SDRAM_REF_CTRL[15:0] REG_REFRESH_RATE parameter taking into account frequency of the device. When a warm reset is applied on the system, the OMAP processor restarts with another OPP and so frequency is not the same. Due to this frequency change, the refresh rate will be too low and could result in an unexpected behavior on the memory side. Workaround: The workaround is to force self-refresh when coming back from the warm reset with the following sequence: • Set EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE to 0x2 • Set EMIF_PWR_MGMT_CTRL[7:4] REG_SR_TIM to 0x0 • Do a dummy read (loads automatically new value of sr_tim) This will reduce the risk of memory content corruption, but memory content can't be guaranteed after a warm reset. This errata is impacted on OMAP4430: 1.0, 2.0, 2.1, 2.2, 2.3 OMAP4460: 1.0, 1.1 OMAP4470: 1.0 OMAP5430: 1.0 Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: R Sricharan <r.sricharan@ti.com> Signed-off-by: Senthilvadivu Guruswamy <svadivu@ti.com>
* OMAP4+: Handle sdram init after warm resetLokesh Vutla2012-07-07-4/+6

* arm/km: use spi claim bus to switch between SPI and NANDValentin Longchamp2012-07-07-40/+13
| | | | | | | | | | | | | | We overwrite these weak functions from the kirkwood spi code to use our own method to be able to switch between the SPI NOR and the NAND flash. This is needed e.g. to update the u-boot. The former command do_spi_toggle can therefore be removed. And the usage of this command is removed from the u-boot update command in the u-boot environment.

* ARM: don't probe PHY address for LaCie boardsSimon Guinot2012-07-07-20/+11
| | | | | | | | | | | | | The command miiphy_read(name, 0xEE, 0xEE, (u16 *) &devadr) always returns 8 for the PHY address. It is the reset value for the PHY Address Register. Obviously, this default value could be incorrect. Moreover, as the PHY address is well known, there is no need to auto-detect it. Now, the PHY address must given as a parameter to the PHY initialization function. Additionally this patch also fixes some aesthetic issues. Signed-off-by: Simon Guinot <simon.guinot@sequanux.org>

| | | | | | | | | | | | | | | The commit "i.mx: fsl_esdhc: add the i.mx6q support" (4692708d) introduces support for the i.MX6Q MMC host controller USDHC. MXC_IPG_PERCLK sets the clock to 66MHz. This seems to be the default clock of the ESDHC IP found in < i.MX6 silicon. However, the default clock for the USDHC IP found in i.MX6 is 200MHz (MXC_ESDHC_CLK). This difference will cause a 3 times higher clock on SD_CLK than expected (see fsl_esdh.c -> set_sysctl()).
