This patch adds needed nodes and properties to support suspend/resume on the MPC8610HPCD boards. There is a dedicated switch (SW9) that is used to wake up the boards. By default the SW9 button is routed to IRQ8, but could be re-routed (via PIXIS) to sreset. With 'no_console_suspend' kernel command line argument specified, the board is also able to wakeup upon serial port input. Signed-off-by:

This patch adds suspend/resume support for MPC8540 and MPC8641D- compatible CPUs. To reach sleep state, we just write the SLP bit into the PM control and status register. So far we don't support Deep Sleep mode as found in newer MPC85xx CPUs (i.e. MPC8536). It can be relatively easy implemented though, and for it we reserve 'mem' suspend type. Signed-off-by:

So far the driver is used to reset QE upon resume, which is needed on 85xx. Later we can move some QE initialization steps into probe(). Signed-off-by:

This patch adds QE buffer descriptors mode support for the spi_mpc8xxx driver, and as a side effect we now support CPM1 and CPM2 SPI controllers. That means that today we support almost all MPC SPI controllers: - MPC834x-style controllers (support PIO mode only); - CPM1 and CPM2 controllers (support DMA mode only); - QE SPI controllers in CPU mode (PIO mode with shift quirks); - QE SPI controllers in buffer descriptors (DMA) mode; The only controller we don't currently support is a newer eSPI (with a dedicated chip selects and a bit different registers map).

This is needed to avoid ugly #ifdefs in drivers. Also update fsl_qe_udc driver so that now it doesn't define its own versions that cause build breakage when the generic stubs are used. Signed-off-by:

The bits are generic to CPM devices, so let's move them to the common header file, so drivers won't need to privately reintroduce another bunch of the same bits (as we can't include cpm2.h header together with cpm1.h). Signed-off-by:

struct mcc defined in both immap_qe.h and immap_cpm2.h, so they will conflic when included in a single file. The mcc struct is easy to deal with, since it isn't used in any driver (yet), so let's just rename QE version to qe_mcc. The ucb_ctlr is a bit trickier, since it is used by fsl_qe_udc driver, and the driver supports both CPM and QE UDCs, plus the QE version is used to form a bigger immap struct. I don't want to touch too much of USB code in this series, so for now let's just copy most generic version into the common cpm.h header, later we'll create cpm_usb.h where we'll place common USB structs that are used by QE/CPM UDC and QE Host drivers (FHCI). And as for the structs in qe.h and cpm2.h, just prefix them with qe_ and cpm_. Signed-off-by:

Anton Vorontsov authored
When cpm2.h included into spi_mpc8xxx driver, the SPI defines in the header conflict with defines in the driver. We don't need them in the header file, so remove them. Plus remove "struct spi", we'll use a better version in the driver. Signed-off-by:

P1020 is another member of Freescale QorIQ series of processors. It is an e500 based dual core SOC. Being a scaled down version of P2020 it has following differences from P2020: - 533MHz - 800MHz core frequency. - 256Kbyte L2 cache - Ethernet controllers with classification capabilities(new controller). From board perspective P1020RDB is same as P2020RDB. Signed-off-by:

It appears that QE shuts down on all MPC85xx CPUs (i.e. MPC8568 and MPC8569) and thus needs reset upon resume. So modify qe_alive_during_sleep() to account that. Signed-off-by:
-
Anton Vorontsov authored
For MPC8569 CPUs we'll need to reset QE after each suspend, so make qe_reset() code path suitable for repeated invocation, that is: - Don't initialize rheap structures if already initialized; - Don't allocate muram for SDMA if already allocated, just reinitialize registers with previously allocated muram offset; - Remove __init attributes from qe_reset() and cpm_muram_init(); Signed-off-by:

This patch creates the dts files for each core and splits the devices between the two cores for P2020RDB. core0 has memory, L2, i2c, spi, dma1, usb, eth0, eth1, crypto, global-util, pci0, core1 has L2, dma2, eth0, pci1, msi. MPIC is shared between two cores but each core will protect its interrupts from other core by using "protected-sources" of mpic. Signed-off-by:

Rafael debugged a resume-time hang (with oopses in workqueue handling) on his laptop that was due to the 'waker' workqueue entry being disconnected and then released without the workqueue entry having been synchronized. Several people were involved, with Oleg Nesterov doing a debugging patch showing what workqueue entry was corrupt etc. This was a regression introduced by commit 7bee549e ("Bluetooth: Add USB autosuspend support to btusb driver") as Rafael points out (not actually bisected, but it became clear once the bug was found).

There is a problem where iget5_locked will look for an inode, not find it, and then subsequently try to allocate it. Another CPU will have raced in and allocated the inode instead, so when iget5_locked gets the inode spin lock again and does a search, it finds the new inode. So it goes ahead and calls destroy_inode on the inode it just allocated. The problem is we don't set BTRFS_I(inode)->root until the new inode is completely initialized. This patch makes us set root to NULL when alloc'ing a new inode, so when we get to btrfs_destroy_inode and we see that root is NULL we can just free up the memory and continue on. This fixes the panic http://www.kerneloops.org/submitresult.php?number=812690 Thanks, Signed-off-by:
