As per HDA spec section 4.3 - Codec Discovery, the software shall wait for atleast 521usec for codec to respond after link reset. With the multi-link capability each link is turned ON/OFF individually. Link controller drives reset signal when it is turned ON.

Split snd_hda_codec_new into two separate functions. snd_hda_codec_device_init allocates memory and registers with bus. snd_hda_codec_device_new initialializes the fields and performs snd_device_new. This enables reuse of legacy HDA codec drivers as ASoC codec drivers. In addition mark some functions with EXPORT_SYMBOL_GPL so that it can be called by ASoC wrapper around the legacy HDA driver (hdac_hda).

Remove memory allocation within snd_hdac_ext_bus_device_init, to make its behaviour identical to snd_hdac_bus_device_init. So that caller can allocate the parent data structure containing hdac_device. This API change helps in reusing the legacy HDA codec drivers with ASoC platform drivers.

Add machine driver for Intel platforms (SKL/KBL/BXT/APL) with HDA and iDisp codecs. This patch adds support for only iDisp (HDMI/DP) codec.

When no I2S based codec entries are found in the BIOS, check if there are any HDA codecs detected on the bus. Based on the number of codecs found take appropriate action in machine driver. If there are two HDA codecs i.e. iDisp + HDA found on the bus, register DAIs and DAI links for both. If only one codec i.e. iDisp is found then load only iDisp machine driver.

We need register/enable irq handler before init_caps, where we are doing codec probing for HDMI/HDA, otherwise the probing may fail. We also need to use PCI_IRQ_LEGACY mode at the moment, as PCI_IRQ_MSI doesn't work for HDMI yet, may need more debug to fix it. Signed-off-by: Keyon Jie <yang.jie@linux.intel.com>
This patch doesn't replace struct sof_intel_hda_dev with hda_bus, but embed hda_bus in sof_intel_hda_dev. It's becasue there are a few memebers of sof_intel_hda_dev are not in hda_bus. Host streams are managed by hdac_bus's stream_list now. Compiling okay. But not test yet. May have conflict with Keyon's PR today. I'll rebase and merge it to Keyon's PR later. Signed-off-by: Mengdong Lin <mengdong.lin@linux.intel.com>
In previous patch, hdac_bus is used to manage the host streams, but the stream structure is still struct sof_intel_hda_stream. This patch replaces struct sof_intel_hda_stream with hdac_ext_stream, but the stream management is still using BSD implementation of SOF, not the GPL implemenation of HDA core. Please note that - hdac_bus maintains a stream list of hdac_stream, which is embeded in struct hdac_ext_stream. - pcm runtime's private data points to hdac_stream, not hdac_ext_stream. Compiling okay. Not tested yet. Signed-off-by: Mengdong Lin <mengdong.lin@linux.intel.com>

Define a new kernel config item SND_SOC_SOF_BYPASS_DSP, which depends on SND_SOC_SOF_HDA. To test SOF in legacy HDA mode, we can enable both SND_SOC_SOF_HDA and SND_SOC_SOF_BYPASS_DSP. And then SOF will bypass audio DSP and not firmware will be downloaded. Later patches will disable more DSP-specific operations not needed by legacy HD-A mode by checking if SND_SOC_SOF_BYPASS_DSP is enabled.

[ Upstream commit e1de943 ] Recent work with KASan exposed the folling hard-coded bitmask in arch/arm/mm/proc-macros.S: bic rd, sp, #8128 bic rd, rd, thesofproject#63 This forms the bitmask 0x1FFF that is coinciding with (PAGE_SIZE << THREAD_SIZE_ORDER) - 1, this code was assuming that THREAD_SIZE is always 8K (8192). As KASan was increasing THREAD_SIZE_ORDER to 2, I ran into this bug. Fix it by this little oneline suggested by Ard: bic rd, sp, #(THREAD_SIZE - 1) & ~63 Where THREAD_SIZE is defined using THREAD_SIZE_ORDER. We have to also include <linux/const.h> since the THREAD_SIZE expands to use the _AC() macro.

The coreboot_table driver registers a coreboot bus while probing a "coreboot_table" device representing the coreboot table memory region. Probing this device (i.e., registering the bus) is a dependency for the module_init() functions of any driver for this bus (e.g., memconsole-coreboot.c / memconsole_driver_init()). With synchronous probe, this dependency works OK, as the link order in the Makefile ensures coreboot_table_driver_init() (and thus, coreboot_table_probe()) completes before a coreboot device driver tries to add itself to the bus. With asynchronous probe, however, coreboot_table_probe() may race with memconsole_driver_init(), and so we're liable to hit one of these two: 1. coreboot_driver_register() eventually hits "[...] the bus was not initialized.", and the memconsole driver fails to register; or 2. coreboot_driver_register() gets past #1, but still races with bus_register() and hits some other undefined/crashing behavior (e.g., in driver_find() [1]) We can resolve this by registering the bus in our initcall, and only deferring "device" work (scanning the coreboot memory region and creating sub-devices) to probe().

Fix niu_try_msix() to not cause a fatal trap on sparc systems. Set PCI_DEV_FLAGS_MSIX_TOUCH_ENTRY_DATA_FIRST on the struct pci_dev to work around a bug in the hardware or firmware. For each vector entry in the msix table, niu chips will cause a fatal trap if any registers in that entry are read before that entries' ENTRY_DATA register is written to. Testing indicates writes to other registers are not sufficient to prevent the fatal trap, however the value does not appear to matter. This only needs to happen once after power up, so simply rebooting into a kernel lacking this fix will NOT cause the trap.

This PR is to skip firmware download if SOF is working in legacy HD-A mode. User can use Kconfig to decide whether to put SOF in legacy mode. So the patches are okay for topic/hdac branch.
