2020-07-02tpm_tis_spi: Prefer async probeDouglas Anderson
On a Chromebook I'm working on I noticed a big (~1 second) delay during bootup where nothing was happening. Right around this big delay there were messages about the TPM: [ 2.311352] tpm_tis_spi spi0.0: TPM ready IRQ confirmed on attempt 2 [ 3.332790] tpm_tis_spi spi0.0: Cr50 firmware version: ... I put a few printouts in and saw that tpm_tis_spi_init() (specifically tpm_chip_register() in that function) was taking the lion's share of this time, though ~115 ms of the time was in cr50_print_fw_version(). Let's make a one-line change to prefer async probe for tpm_tis_spi. There's no reason we need to block other drivers from probing while we load. NOTES: * It's possible that other hardware runs through the init sequence faster than Cr50 and this isn't such a big problem for them. However, even if they are faster they are still doing _some_ transfers over a SPI bus so this should benefit everyone even if to a lesser extent. * It's possible that there are extra delays in the code that could be optimized out. I didn't dig since once I enabled async probe they no longer impacted me.

2020-07-02tpm: ibmvtpm: Wait for ready buffer before probing for TPM2 attributesDavid Gibson
The tpm2_get_cc_attrs_tbl() call will result in TPM commands being issued, which will need the use of the internal command/response buffer. But, we're issuing this *before* we've waited to make sure that buffer is allocated. This can result in intermittent failures to probe if the hypervisor / TPM implementation doesn't respond quickly enough. I find it fails almost every time with an 8 vcpu guest under KVM with software emulated TPM. To fix it, just move the tpm2_get_cc_attrs_tlb() call after the existing code to wait for initialization, which will ensure the buffer is allocated.

2020-07-02tpm_tis_spi: Don't send anything during flow controlDouglas Anderson
During flow control we are just reading from the TPM, yet our spi_xfer has the tx_buf and rx_buf both non-NULL which means we're requesting a full duplex transfer. SPI is always somewhat of a full duplex protocol anyway and in theory the other side shouldn't really be looking at what we're sending it during flow control, but it's still a bit ugly to be sending some "random" data when we shouldn't. The default tpm_tis_spi_flow_control() tries to address this by setting 'phy->iobuf[0] = 0'. This partially avoids the problem of sending "random" data, but since our tx_buf and rx_buf both point to the same place I believe there is the potential of us sending the TPM's previous byte back to it if we hit the retry loop. Another flow control implementation, cr50_spi_flow_control(), doesn't address this at all. Let's clean this up and just make the tx_buf NULL before we call flow_control(). Not only does this ensure that we're not sending any "random" bytes but it also possibly could make the SPI controller behave in a slightly more optimal way. NOTE: no actual observed problems are fixed by this patch--it's was just made based on code inspection.

2020-07-02tpm: Fix TIS locality timeout problemsJames Bottomley
It has been reported that some TIS based TPMs are giving unexpected errors when using the O_NONBLOCK path of the TPM device. The problem is that some TPMs don't like it when you get and then relinquish a locality (as the tpm_try_get_ops()/tpm_put_ops() pair does) without sending a command. This currently happens all the time in the O_NONBLOCK write path. Fix this by moving the tpm_try_get_ops() further down the code to after the O_NONBLOCK determination is made. This is safe because the priv->buffer_mutex still protects the priv state being modified.

2020-07-01net: dsa: microchip: enable ksz9893 via i2c in the ksz9477 driverHelmut Grohne
The KSZ9893 3-Port Gigabit Ethernet Switch can be controlled via SPI, I²C or MDIO (very limited and not supported by this driver). While there is already a compatible entry for the SPI bus, it was missing for I²C.

2020-07-01drm/i915/dp: Correctly advertise HBR3 for GEN11+Matt Atwood
intel_dp_set_source_rates() calls intel_dp_is_edp(), which is unsafe to use before encoder_type is set. This caused GEN11+ to incorrectly strip HBR3 from source rates for edp. Move intel_dp_set_source_rates() to after encoder_type is set. Add comment to intel_dp_is_edp() describing unsafe usages. v2: Alter intel_dp_set_source_rates final position (Ville/Manasi). Remove outdated comment (Ville). Slight optimization of control flow in intel_dp_init_connector. Slight rewording in commit message.
