* rtc: ds1307: support m41t0 variantStefan Agner2017-04-14
| | | | | | | | | | | | | | | | | The m41t0 variant is very similar to the already supported m41t00 variant, with the notable exception of the oscillator fail bit. The data sheet notes: If the oscillator fail (OF) bit is internally set to a '1,' this indicates that the oscillator has either stopped, or was stopped for some period of time and can be used to judge the validity of the clock and date data. The bit will get cleared with a regular write of the system time, so no changes are needed to clear it.

* rtc: cmos: Do not assume irq 8 for rtc when there are no legacy irqsHans de Goede2017-04-14
| | | | | | | | | | | | | | | | | | | | | | On some systems (e.g. Intel Bay Trail systems) the legacy PIC is not used, in this case virq 8 will be a random irq, rather then hw_irq 8 from the PIC. Requesting virq 8 in this case will not help us to get alarm irqs and may cause problems for other drivers which actually do need virq 8, for example on an Asus Transformer T100TA this leads to: [ 28.745155] genirq: Flags mismatch irq 8. 00000088 (mmc0) vs. 00000080 (rtc0) <snip oops> [ 28.753700] mmc0: Failed to request IRQ 8: -16 [ 28.975934] sdhci-acpi: probe of 80860F14:01 failed with error -16 This commit fixes this by making the rtc-cmos driver continue without using an irq rather then claiming irq 8 when no irq is specified in the pnp-info and there are no legacy-irqs.

* x86: i8259: export legacy_pic symbolHans de Goede2017-04-14
| | | | | | | | | | | | | | | | | | | | The classic PC rtc-coms driver has a workaround for broken ACPI device nodes for it which lack an irq resource. This workaround used to unconditionally hardcode the irq to 8 in these cases. This was causing irq conflict problems on systems without a legacy-pic so a recent patch added an if (nr_legacy_irqs()) guard to the workaround to avoid this irq conflict. nr_legacy_irqs() uses the legacy_pic symbol under the hood causing an undefined symbol error if the rtc-cmos code is build as a module. This commit exports the legacy_pic symbol to fix this.

Before this patch, the internal ESRCH netlink error code was propagated to userspace, which is quite misleading.

First one corrects the buffer size we populate a register with. The register is designed to be used for scatter transfers which the driver (and most FWs) don't support so it's not critical. The other one for DMA direction is mostly cosmetic, DMA API doesn't seem to care today about the precise direction in sync calls. ==================== Signed-off-by: David S.

FW should only be told about the buffer space it can DMA to, that is without the build_skb() headroom and tailroom. Note: firmware applications should validate the buffers against both MTU and free list buffer size so oversized packets would not pass through the NIC anyway.

The code now checks to see if the adapter needs to be brought out of reset (where as before it was doing an IDM write to bring it out of reset regardless of whether it was in reset or not). Also, removed unnecessary usleeps (as there is already a read present to flush the IDM writes).
