2016-01-08mtd: jz4780_nand: replace if/else blocks with switch/caseBrian Norris
Using switch/case helps make this logic more clear and more robust. With this structure: * it's clear that this driver only support ECC_{HW,SOFT,SOFT_BCH}; and * we can sanely handle new ECC unsupported modes (right now, this code makes incorrect assumptions about the possible values in the nand_ecc_modes_t enum; e.g., what happens with NAND_ECC_HW_OOB_FIRST?)

2016-01-08libata: skip debounce delay on link resumeDanesh Petigara
The link resume logic uses a 200msec delay while debouncing the SControl register. The rationale behind that delay is to accommodate some PHYs that behave badly if their SStatus/ SControl registers are pounded immediately on resume. The Broadcom STB SATA PHY does not seem to have this issue. This patch introduces a new link flag that allows platforms to skip the debounce delay if it isn't needed.

sleeps (<20 ms) Since msleep() may sleep longer than intended time for values less than 20ms, this patch allows the use of usleep_range for waits less that 20ms. usleep_range is a finer precision implementation of msleep and is designed to be a drop-in replacement for udelay where a precise sleep/busy-wait is unnecessary.

2016-01-08i40e: Look up MAC address in Open Firmware or IDPROMSowmini Varadhan
This is the i40e equivalent of commit c762dff24c06 ("ixgbe: Look up MAC address in Open Firmware or IDPROM"). As with that fix, attempt to look up the MAC address in Open Firmware on systems that support it, and use IDPROM on SPARC if no OF address is found. In the case of the i40e there is an assumption that the default mac address has already been set up as the primary mac filter on probe, so if this filter is obtained from the Open Firmware or IDPROM, an explicit write is needed via i40e_aq_mac_address_write() and i40e_aq_add_macvlan() invocation. The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure tracks whether a platform-specific mac address was found, in which case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan() will be triggered.

2016-01-07serial: sh-sci: Remove cpufreq notifier to fix crash/deadlockGeert Uytterhoeven
The BSP team noticed that there is spin/mutex lock issue on sh-sci when CPUFREQ is used. The issue is that the notifier function may call mutex_lock() while the spinlock is held, which can lead to a BUG(). This may happen if CPUFREQ is changed while another CPU calls clk_get_rate(). Taking the spinlock was added to the notifier function in commit e552de2413edad1a ("sh-sci: add platform device private data"), to protect the list of serial ports against modification during traversal. At that time the Common Clock Framework didn't exist yet, and clk_get_rate() just returned clk->rate without taking a mutex. Note that since commit d535a2305facf9b4 ("serial: sh-sci: Require a device per port mapping."), there's no longer a list of serial ports to traverse, and taking the spinlock became superfluous. To fix the issue, just remove the cpufreq notifier: 1. The notifier doesn't work correctly: all it does is update stored clock rates; it does not update the divider in the hardware. The divider will only be updated when calling sci_set_termios(). I believe this was broken back in 2004, when the old drivers/char/sh-sci.c driver (where the notifier did update the divider) was replaced by drivers/serial/sh-sci.c (where the notifier just updated port->uartclk). Cfr. full-history-linux commits 6f8deaef2e9675d9 ("[PATCH] sh: port sh-sci driver to the new API") and 3f73fe878dc9210a ("[PATCH] Remove old sh-sci driver"). 2. On modern SoCs, the sh-sci parent clock rate is no longer related to the CPU clock rate anyway, so using a cpufreq notifier is futile.

2016-01-07scsi: add Synology to 1024 sector blacklistMike Christie
Another iscsi target that cannot handle large IOs, but does not tell us a limit. The Synology iSCSI targets report: Block limits VPD page (SBC): Write same no zero (WSNZ): 0 Maximum compare and write length: 0 blocks Optimal transfer length granularity: 0 blocks Maximum transfer length: 0 blocks Optimal transfer length: 0 blocks Maximum prefetch length: 0 blocks Maximum unmap LBA count: 0 Maximum unmap block descriptor count: 0 Optimal unmap granularity: 0 Unmap granularity alignment valid: 0 Unmap granularity alignment: 0 Maximum write same length: 0x0 blocks and the size of the command it can handle seems to depend on how much memory it can allocate at the time. This results in IO errors when handling large IOs. This patch just has us use the old 1024 default sectors for this target by adding it to the scsi blacklist. We do not have good contacs with this vendors, so I have not been able to try and fix on their side. I have posted this a long while back, but it was not merged.

2016-01-08USB / PM: Allow USB devices to remain runtime-suspended when sleepingTomeu Vizoso
Have dev_pm_ops.prepare return 1 for USB devices and ports so that USB devices can remain runtime-suspended when the system goes to a sleep state, if their wakeup state is correct and they have runtime PM enabled.

2016-01-08PM / sleep: Go direct_complete if driver has no callbacksTomeu Vizoso
If a suitable prepare callback cannot be found for a given device and its driver has no PM callbacks at all, assume that it can go direct to complete when the system goes to sleep. The reason for this is that there's lots of devices in a system that do no PM at all and there's no reason for them to prevent their ancestors to do direct_complete if they can support it.

2016-01-08PM / Domains: add setter for dev.pm_domainTomeu Vizoso
Adds a function that sets the pointer to dev_pm_domain in struct device and that warns if the device has already finished probing. The reason why we want to enforce that is because in the general case that can cause problems and also that we can simplify code quite a bit if we can always assume that. This patch also changes all current code that directly sets the dev.pm_domain pointer.

2016-01-08device core: add device_is_bound()Tomeu Vizoso
Adds a function that tells whether a device is already bound to a driver. This is needed to warn when there is an attempt to change the PM domain of a device that has finished probing already. The reason why we want to enforce that is because in the general case that can cause problems and also that we can simplify code quite a bit if we can always assume that.
