Add a device tree entry for the Guruplug Server Plus board. This port was based both on the work done on the dreamplug and the dockstar. It builds, boots and works on my Guruplug Server Plus. Signed-off-by:

This patch adds the DTS file to support the Marvell RD-A370-A1 (Reference Design board) also known as RD-88F6710 board. It is almost entirely similar to the DB-A370 board except that the first Ethernet PHY is SGMII-wired and the second is a switch which is RGMII-wired. Signed-off-by:

In the beginning of DT for Dove it was reasonable to have it close to non-DT code. With improved DT support, it became more and more difficult to not break non-DT while changing DT code. This patch splits up DT board setup and introduces a DOVE_LEGACY config to allow to remove legacy code for DT-only kernels. Signed-off-by:

This refreshes the dove_defconfig, and adds: PRINTK_TIME DEVTMPFS EXT4 They're quite useful, and allows booting a cubox ubuntu rootfs on SD card, since that by default uses ext4. The rest of the churn is due to options and defaults moving around, no functional difference. Signed-off-by:

Now that SDIO is instantiated via DT, and the SDIO DT node has a clocks property, we no longer need a C coded clock alias. Remove it. Signed-off-by:

The OpenBlocks AX3-4 platform has several LEDs, so it sounds wise to enable LED support in mvebu_defconfig. We anticipate that more platforms using Marvell EBU SoCs will have LEDs in the future. Signed-off-by:

The Globalscale Mirabox platform, based on the Armada 370 from Marvell, has a SD8787 Wireless/Bluetooth chip connected on the SDIO interface. Now that the mvsdio has a Device Tree binding, and the necessary Device Tree informations have been added at the SoC and board level, let's enable the btmrvl driver for the Bluetooth part of the SD8787 chip. For now, the driver gets probed correctly, detects the device but apparently fails to push the firmware to the device: Bluetooth: vendor=0x2df, device=0x911a, class=255, fn=2 Bluetooth: FW failed to be active in time! Bluetooth: Downloading firmware failed! Bluetooth: vendor=0x2df, device=0x911b, class=255, fn=3 Bluetooth: FW failed to be active in time! Bluetooth: Downloading firmware failed! This will have to be investigated separately. Signed-off-by:

However, scanning Wifi networks doesn't work for now, with a 'CMD_RESP: cmd 0x6 error, result=0x1' message. This will have to be investigated separately. Signed-off-by:

On many Marvell SoCs, the pins used for the SDIO interface are part of the MPP pins, that are muxable pins. In order to get the muxing of those pins correct, this commit integrates the mvsdio driver with the pinctrl infrastructure by calling devm_pinctrl_get_select_default() during ->probe(). Note that we permit this function to fail because not all Marvell platforms have yet been fully converted to using the pinctrl infrastructure. Signed-off-by:

This patch adds a simple Device Tree binding for the mvsdio driver, as well as the necessary documentation for it. Compatibility with non-DT platforms is preserved, by keeping the platform_data based initialization. We introduce a small difference between non-DT and DT platforms: DT platforms are required to provide a clocks = <...> property, which the driver uses to get the frequency of the clock that goes to the SDIO IP. The behaviour on non-DT platforms is kept unchanged: a clock reference is not mandatory, but the clock frequency must be passed in the "clock" field of the mvsdio_platform_data structure.

The MMC core subsystem provides in drivers/mmc/core/slot-gpio.c a nice set of helper functions to simplify the management of the card detect GPIO in MMC host drivers. This patch migrates the mvsdio driver to using those helpers, which will make the ->probe() code simpler, and therefore ease the process of adding a Device Tree binding for this driver.

Kevin Liu authored
Current code missed disabling interrupts before free irq which is shared. Notice below comments for function free_irq (kernel/irq/manage.c): On a shared IRQ the caller must ensure the interrupt is disabled on the card it drives before calling this function. Original code has below issue during suspend/resume when multiple SD hosts share the same IRQ: 1. Assume there are two hosts (host1 for emmc while host2 for sd) share the same mmc irq. 2. When system suspend, host2 will be suspended before host1. So the sequence is below: step1: irq handler for host2 removed -> step2: irq handler for host1 removed and irq disabled -> ... system suspended ... ... system resumed ... step3: irq enabled and the irq handler for host1 restored -> step4: irq handler for host2 restored 3. So there is the buggy time slot that the irq is enabled but the irq handler for host2 is removed. Then host2 interrupt can be triggered but can't be handled at that moment. Signed-off-by:

When current request is running on the bus and if next request fetched by mmcqd is NULL, mmc context (mmcqd thread) gets blocked until the current request completes. This means that if new request comes in while the mmcqd thread is blocked, this new request can not be prepared in parallel to current ongoing request. This may result in delaying the new request execution and increase it's latency. This change allows to wake up the MMC thread on new request arrival. Now once the MMC thread is woken up, a new request can be fetched and prepared in parallel to the current running request which means this new request can be started immediately after the current running request completes. With this change read throughput is improved by 16%. Signed-off-by:

Make error reporting in the driver more verbose. This patch is based on an earlier work by Teppei Kamijou, but we try to not add any new error messages to the log in the normal case to avoid confusing the user, and also add a few more dev_dbg() calls. Signed-off-by:

The INT_BUFWEN IRQ often arrives with other bits set too. If they are not cleared, an additional IRQ can be triggered, sometimes also after the MMC request has already been completed. This leads to block I/O errors. Earlier Teppei Kamijou also observed these additional interrupts and proposed to explicitly wait for them. This patch chooses an alternative approach of clearing all active bits immediately, when processing the main interrupt. Reported-by:
