The OLPC XO-1.75 laptop includes a SDHCI controller which is 1.8v capable, and it truthfully reports so in its capabilities. This alternate voltage is used for driving new "UHS-I" SD cards at their full speed. However, what the controller doesn't know is that the motherboard physically doesn't have a 1.8v supply available, so attempting to switch to the 1.8v level will result in a situation that cannot be recovered from without physically replugging the SD card. Add a device tree flag that can be used on systems like these, and hook it up to the equivalent SDHCI quirk.

HSMMC IP on AM33xx need a special setting to handle High-speed cards. Other platforms like TI81xx, OMAP4 may need this as-well. This depends on the HSMMC IP timing closure done for the high speed cards. From AM335x TRM (SPRUH73F - 18.3.12 Output Signals Generation): The MMC/SD/SDIO output signals can be driven on either falling edge or rising edge depending on the SD_HCTL[2] HSPE bit. This feature allows to reach better timing performance, and thus to increase data transfer frequency. There are few pre-requisites for enabling the HSPE bit - Controller should support High-Speed-Enable Bit and - Controller should not be using DDR Mode and - Controller should advertise that it supports High Speed in capabilities register and - MMC/SD clock coming out of controller > 25MHz Signed-off-by: NHebbar, Gururaja <gururaja.hebbar@ti.com> Signed-off-by: NVenkatraman S <svenkatr@ti.com> Signed-off-by: NChris Ball <cjb@laptop.org>

由 Shiraz Hashim 提交于
SPEAr3xx architecture includes shared/multiplexed irqs for certain set of devices. The multiplexor provides a single interrupt to parent interrupt controller (VIC) on behalf of a group of devices. There can be multiple groups available on SPEAr3xx variants but not exceeding 4. The number of devices in a group can differ, further they may share same set of status/mask registers spanning across different bit masks. Also in some cases the group may not have enable or other registers. This makes software little complex. Present implementation was non-DT and had few complex data structures to decipher banks, number of irqs supported, mask and registers involved. This patch simplifies the overall design and convert it in to DT. It also removes all registration from individual SoC files and bring them in to common shirq.c. Also updated the corresponding documentation for DT binding of shirq. Signed-off-by: NShiraz Hashim <shiraz.hashim@st.com> Signed-off-by: NViresh Kumar <viresh.kumar@linaro.org>

In current code the ethernet PLL is not handled correctly. The PLL runs at 500MHz and has different outputs. Only the enet reference clock is implemented. This patch changes the PLL so that it outputs 500MHz and adds the additional outputs as dividers. This now matches the datasheet which says: > This PLL synthesizes a low jitter clock from 24 MHz reference clock. > The PLL outputs a 500 MHz clock. The reference clocks generated by this PLL are: > • Ref_PCIe = 125 MHz > • Ref_SATA = 100 MHz > • Ref_ethernet, which is configurable based on the PLL_ENET[1:0] register field.

This will allow to use gpio for chip select with no modification in the driver binding When use the cs-gpios, the gpio number will be passed via the cs_gpio field and the number of chip select will automatically increased with max(hw cs, gpio cs). So if for example the controller has 2 CS lines, and the cs-gpios property looks like this: cs-gpios = <&gpio1 0 0> <0> <&gpio1 1 0> <&gpio1 2 0>; Then it should be configured so that num_chipselect = 4 with the following mapping: cs0 : &gpio1 0 0 cs1 : native cs2 : &gpio1 1 0 cs3 : &gpio1 2 0 Signed-off-by: NJean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Cc: devicetree-discuss@lists.ozlabs.org Cc: spi-devel-general@lists.sourceforge.net Signed-off-by: NRichard Genoud <richard.genoud@gmail.com> [grant.likely: fixed up type of cs count so min() can do type checking] Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

由 Gregory CLEMENT 提交于
Armada 370 and XP come with an unit called coherency fabric. This unit allows to use the Armada 370/XP as a nearly coherent architecture. The coherency mechanism uses snoop filters to ensure the coherency between caches, DRAM and devices. This mechanism needs a synchronization barrier which guarantees that all the memory writes initiated by the devices have reached their target and do not reside in intermediate write buffers. That's why the architecture is not totally coherent and we need to provide our own functions for some DMA operations. Beside the use of the coherency fabric, the device units will have to set the attribute flag of the decoding address window to select the accurate coherency process for the memory transaction. This is done each device driver programs the DRAM address windows. The value of the attribute set by the driver is retrieved through the orion_addr_map_cfg struct filled during the early initialization of the platform.
