Individual controllers in the chip have\ndrivers that do not support the reset of the registers during suspend,\nand they need to be adapted to handle it.\n\nThe first patch uses the clock wakeup code from the prototype backup\nmode instead of the version integrated in the mainline, as the mainline\nversion is not stable. During a test loop with two-second backup\nsuspend, the mainline version will hang in less than one day, whereas\nthe prototype version has been running the same test for more than a\nweek without hanging.\n\nWhile all these patches are provided in a series, the clock, mtd,\nusb, pwm and mfd patch do not depend on each other.\n\nChanges in v2:\n* drop the IIO patch duplicating existing code\n* determine the number of programmable clocks to save dynamically\n* declare a required local variable in the tty/serial patch\n\nChanges in v3:\n* drop dev_printk changes for PMECC\n* rework the resume code for PMECC\n* improve comments on PMC clock handling\n\nRomain Izard (8):\n clk: at91: pmc: Wait for clocks when resuming\n clk: at91: pmc: Save SCSR during suspend\n clk: at91: pmc: Support backup for programmable clocks\n mtd: nand: atmel: Avoid ECC errors when leaving backup mode\n ehci-atmel: Power down during suspend is normal\n pwm: atmel-tcb: Support backup mode\n atmel_flexcom: Support backup mode\n tty/serial: atmel: Prevent a warning on suspend\n\n drivers/clk/at91/clk-programmable.c | 2 +\n drivers/clk/at91/pmc.c | 63 ++++++++++++++++++++++++++-----\n drivers/clk/at91/pmc.h | 2 +\n drivers/mfd/atmel-flexcom.c | 65 ++++++++++++++++++++++++--------\n drivers/mtd/nand/atmel/nand-controller.c | 3 ++\n drivers/mtd/nand/atmel/pmecc.c | 22 +++++++----\n drivers/mtd/nand/atmel/pmecc.h | 1 +\n drivers/pwm/pwm-atmel-tcb.c | 63 ++++++++++++++++++++++++++++++-\n drivers/tty/serial/atmel_serial.c | 13 +++++++\n drivers/usb/host/ehci-atmel.c | 3 +-\n 10 files changed, 201 insertions(+), 36 deletions(-)" }
