2016-09-26mmc: davinci: remove incorrect NO_IRQ useArnd Bergmann
platform_get_irq() returns an error value on failure, not NO_IRQ, so the error handling here could never work. This changes the code to propagate the error value instead. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2016-05-02mmc: davinci: prepare clockDavid Lechner
When trying to use this driver with the common clock framework, enabling the clock fails because it was not prepared. This fixes the problem by calling clk_prepare and clk_enable in a single function. Ditto for clk_disable_unprepare.

Suspend and resume of cards are being handled from the protocol layer and consequently the mmc_suspend|resume_host APIs are deprecated.

2012-03-27mmc: davinci: Poll status for small size transfersIdo Yariv
For small size non-dma sdio transactions, it is sometimes better to poll the mmc host and avoid interrupts altogether. Polling lowers the number of interrupts and context switches. Tests have shown that for small transactions, only a few polling iterations are needed, so this is worth while.

2012-03-27mmc: davinci: Eliminate spurious interruptsIdo Yariv
The davinci mmc interrupt handler fills the fifo, as long as the DXRDY or DRRDY bits are set in the status register. If interrupts fire during this loop, they will be handled by the handler, but the interrupt controller will still buffer these. As a result, the handler will be called again to serve these needlessly. In order to avoid these spurious interrupts, keep interrupts masked while filling the fifo.

2010-05-27davinci: mmc: pass number of SG segments as platform dataSudhakar Rajashekhara
On some platforms like DM355, the number of EDMA parameter slots available for EDMA_SLOT_ANY usage are few. In such cases, if MMC/SD uses 16 slots for each instance of MMC controller, then the number of slots available for other modules will be very few. By passing the number of EDMA slots to be used in MMC driver from platform data, EDMA slots available for other purposes can be controlled. Most of the platforms will not use this platform data variable. But on DM355, as the number of EDMA resources available is limited, the number of scatter- gather segments used inside the MMC driver can be 8 (passed as platform data) instead of 16. On DM355, when the number of scatter-gather segments was reduced to 8, I saw a performance difference of about 0.25-0.4 Mbytes/sec during write. Read performance variations were negligible.
